Mandel's campaign was singled out by the independent fact-checking group Politifact for its "casual relationship with the truth" and its tendency to "double down" after inaccuracies were pointed out. The fact-checking group wrote: "For all the gifts Mandel has, from his compelling personal narrative as an Iraq war veteran to a well-oiled fundraising machine, whoppers are fast becoming a calling card of his candidacy."


2012 United States Senate election in Ohio, General election, Campaign
Mandel raised $7.2 million through the first quarter of 2012. He had $5.3 million cash on hand, trailing Brown's $6.3 million.

Despite many predictions of a close race, the election was not close. Casey, despite being seen as somewhat vulnerable, went into election night with most analysts thinking he could win. Casey did win by more than expected, which can be traced to several factors. Casey trounced Smith in Philadelphia County, home of Philadelphia. Casey also won the surrounding collar counties of Bucks, Chester, Delaware, and Montgomery, which are seen as vital in statewide elections in Pennsylvania. Casey also performed well in Allegheny County, home of Pittsburgh. Casey also performed well in Erie. Casey also performed strongly in the Scranton area. Smith did well in rural counties, but it wasn't enough to overcome the lead Casey had built in the huge population centers. Casey was sworn in for his second term beginning at noon on January 3, 2013.

The group cited Hatch's support for the Troubled Asset Relief Program, State Children's Health Insurance Program, No Child Left Behind Act, Bridge to Nowhere, and other votes among the reasons why they opposed his re-election. In an interview with Politico, Chaffetz stated, "After 34 years of service, I think most Utahans want a change. They want to thank him for his service, but it's time to move on. And for me personally, I think he's been on the wrong side of a host of major issues." The congressman cited Hatch's vote in favor of Equal Opportunity to Serve Act and the Health Equity and Access Reform Today Act of 1993. However, Chaffetz ultimately decided against a run.

The 2012 United States Senate election in Virginia took place on November 6, 2012, concurrently with the 2012 U.S. presidential election as well as other elections to the United States Senate and House of Representatives and various state and local elections. Incumbent Democratic U.S. Senator Jim Webb retired instead of running for reelection to a second term, and former Democratic Governor of Virginia Tim Kaine won the open seat over Republican former Senator and Governor George Allen. Kaine was unopposed for the Democratic nomination, and the Republicans nominated Allen through a primary on June 12, 2012. Allen had previously held this seat for one term before narrowly losing reelection to Webb in 2006.


2012 United States Senate election in Virginia, Republican primary

Once incumbent U.S. Senator Jim Webb decided to retire, many Democratic candidates were speculated. These included U.S. Congressmen Rick Boucher, Gerry Connolly, Glenn Nye, Tom Perriello and Bobby Scott. However, they all declined and encouraged Kaine to run for the seat, believing he would be by far the most electable candidate. Courtney Lynch, former Marine Corps Officer and Fairfax business consultant and Julien Modica, former CEO of the Brain Trauma Recovery & Policy Institute, eventually withdrew from the election, allowing Kaine to be unopposed in the Democratic primary.

2012 United States Senate election in West Virginia
The 2012 United States Senate election in West Virginia was held on November 6, 2012. In a rematch of the 2010 special election, incumbent Democratic U.S. Senator Joe Manchin won re-election to a first full term against the Republican nominee, John Raese.


2012 United States Senate election in West Virginia, Background
Robert Byrd held this seat in the U.S. Senate since 1959, after having served in the House of Representatives since 1953, making him the longest-serving person in Congress. Byrd led his party in the Senate from 1977 to 1989, as Majority Leader or Minority Leader. Afterward, as the most senior Democrat in the Senate, he served as President pro tempore of the Senate whenever his party was in the majority, including at the time of his death.


2012 United States Senate election in West Virginia, Background
After Byrd's death, West Virginia Secretary of State Natalie Tennant initially announced that a special election would be held on the same day as the regular election for the six-year term. However, that special election was rescheduled to 2010 for it to coincide with the 2010 mid-term elections.


2012 United States Senate election in West Virginia, Background
Governor Joe Manchin made a temporary appointment of Carte Goodwin to the vacant seat. Goodwin was later replaced by Manchin who won the 2010 special election.


2012 United States Senate election in West Virginia, General election, Campaign
Raese filed a rematch against Manchin, arguing that he now had more material to criticize Manchin for. One example is how Manchin lost his long-time endorsement from West Virginians for Life because of his vote against defunding Planned Parenthood, the nation's largest abortion provider. Another example is how he is undecided about whether or not to support Obama's re-election campaign. Senior Obama campaign advisor David Axelrod commented in response, "His concern is about his own political well-being." In addition, he voted against U.S. Congressman Paul Ryan's Republican budget.


2012 United States Senate election in West Virginia, General election, Campaign
Raese wrote an op-ed in the Charleston Gazette saying about Manchin, "Yes, he'll talk like a conservative and act like he's fiscally responsible to appeal to more moderate voters, but under that outward appearance of a lovable rube is the heart of a tax-and-spend liberal."


2012 United States Senate election in West Virginia, General election, Campaign
Raese continued to make controversial statements. In April 2012, he equated smoking bans with Adolf Hitler's yellow badge. He said "in Monongalia County now, I have to put a huge sticker on my buildings to say this is a smoke-free environment. This is brought to you by the government of Monongalia County. Okay? Remember Hitler used to put Star of David on everybody’s lapel, remember that? Same thing." That same day, he referred to President Franklin D. Roosevelt as "Fidel Roosevelt."


2012 United States Senate election in West Virginia, General election, Campaign
Raese didn't apologize for his statements on Hitler saying "I am not going to be intimidated by a bunch of bullshit. I'm not apologizing to anybody or any organization. It's my perfect right to make a speech about meaningful subject matters in this country." He also called rocker Ted Nugent a "patriot" for criticizing President Barack Obama.


2012 United States Senate election in Wisconsin
The 2012 United States Senate election in Wisconsin took place on November 6, 2012, alongside a U.S. presidential election as well as other elections to the United States Senate and House of Representatives and various state and local elections. Incumbent Democratic Senator Herb Kohl retired instead of running for re-election to a fifth term. This was the first open Senate seat in Wisconsin since 1988, when Kohl won his first term.


2012 United States Senate election in Wisconsin
Primary elections were held on August 14, 2012. Congresswoman Tammy Baldwin of Wisconsin's 2nd congressional district ran unopposed in the Democratic primary. The Republican nominee was former Wisconsin Governor and U.S. Secretary of Health and Human Services Tommy Thompson, who won with a plurality in a four-way primary race. In the general election, Baldwin defeated Thompson and won the open seat. She became the first woman elected to represent Wisconsin in the Senate and the first openly gay U.S. senator in history. This is also the first time Thompson lost a statewide race.


2012 United States Senate election in Wisconsin, Background
Incumbent Democratic senator Herb Kohl was re-elected to a fourth term in 2006, beating Republican attorney Robert Lorge by 67% to 30%. Kohl's lack of fundraising suggested his potential retirement. There was speculation that Kohl might decide to retire so as to allow Russ Feingold, who lost his re-election bid in 2010, to run again, although Mike Tate, chairman of the Wisconsin Democratic Party, dismissed speculation about Kohl's potential retirement. Ultimately, Kohl announced in May 2011 that he would not run for re-election in 2012.


2012 United States Senate election in Wisconsin, Democratic primary
Despite speculation that Kohl would retire to make way for his former Senate colleague Russ Feingold, who had been unseated in 2010, Feingold chose not to enter the race. Other potential candidates also declined to run, so Baldwin was unopposed in the Democratic primary.


2012 United States Senate election in Wisconsin, Republican primary
Congressman and House Budget Committee Chairman Paul Ryan stated he would not run if Kohl sought reelection, but would contemplate a run if Kohl retired. Ryan later stated that he was "95 percent sure" that he would not run. He was later chosen as the Republican nominee for vice president by presidential nominee Mitt Romney.


2012 United States Senate election in Wisconsin, Republican primary
Six candidates declared for the seat, although two later withdrew. The contest turned out to be a four-way fight and although a large majority of Republican primary voters consistently expressed a preference for a nominee "more conservative" than Tommy Thompson, Eric Hovde and Mark Neumann split the conservative vote, allowing Thompson to narrowly prevail with a plurality of the vote.


2012 United States Senate election in Wisconsin, General election, Debates
Baldwin and Thompson agreed to three debates: September 28, October 18 and 26, all broadcast statewide, and nationwide through C-SPAN.


2012 United States Senate election in Wisconsin, General election, Debates

The third debate originated from Eckstein Hall on the campus of Marquette University Law School and was coordinated by WISN-TV in Milwaukee. It aired on that station and across the state's other ABC affiliated stations.


2012 United States Senate election in Wisconsin, Aftermath
Brian Schimming, the vice chairman of the Wisconsin Republican Party, partly blamed Thompson's defeat on the fact that he had to face a competitive primary whereas Baldwin was unopposed for the Democratic nomination: "[Thompson] blew all his money going through the primary. So when he gets through the primary, it was like three weeks before he was up on the air. [ Baldwin] piled on immediately." He claimed "If [Thompson] hadn't had as ugly a primary, we could have won that seat."


2012 United States Senate election in Wyoming
The 2012 United States Senate election in Wyoming took place on November 6, 2012, alongside a U.S. presidential election as well as other elections to the United States Senate and House of Representatives and various state and local elections.

2012 United States Senate elections, Final predictions before the election
The table below gives an overview of some final predictions of the November general elections by several well-known institutes and people. While there were very few mistakes (predictions in the wrong direction; essentially only Montana and North Dakota, by both Sabato's Crystal Ball and FiveThirtyEight), FiveThirtyEight and Princeton Election Consortium had 2-4 races in the Lean categories and no tossups, whereas all other sources had at least eleven races in the middle three categories, and in particular many Tossup races.


2012 United States Senate elections, Arizona
Three-term incumbent and Senate Minority Whip Republican Jon Kyl, who was re-elected in 2006 with 53% of the vote, announced he would not seek a fourth term in 2012. Republican Representative Jeff Flake won the August 28 primary with 69.1% of the vote, against three contenders, including real estate investor Wil Cardon who polled 21.2%. On the Democratic side, former U.S. Surgeon General Richard Carmona won the primary election, which was held August 28, 2012.


2012 United States Senate elections, Arizona
Preliminary general election results showed Flake leading 49.7%-45.7%, but 439,961 early votes had yet to be counted. The official results, as tabulated by the Secretary of State, showed a slightly smaller win for Flake. Flake won the election with 49.7% of the vote against Carmona's 46.2% and Victor's 4.6%.


2012 United States Senate elections, California
Incumbent Democrat Dianne Feinstein was re-elected. The primary election on June 5 took place under California's new blanket primary, where all candidates appear on the same ballot, regardless of party. In the primary, voters voted for any candidate listed, or write-in any other candidate. The top two finishers — regardless of party — advanced to the general election in November, even if a candidate managed to receive a majority of the votes cast in the June primary. In the primary, less than 15% of the total 2010 census population voted. Incumbent Democrat Dianne Feinstein finished first in the blanket primary with 49.5% of the vote. The second-place finisher was Republican candidate and autism activist Elizabeth Emken, who won 12.7% of the vote.


2012 United States Senate elections, California
Feinstein and Emken contested the general election on November 6, with Feinstein winning re-election in a landslide, by 62.5% to 37.5%. Feinstein's 7.86 million votes set the all-time record for the most votes cast for one candidate in one state in one election, beating senator Barbara Boxer's 6.96 million votes in 2004. This record was held until the 2016 presidential election in California, when Hillary Clinton won 8.75 million votes in the state.


2012 United States Senate elections, Connecticut
Incumbent Joe Lieberman, an independent who caucused with the Democratic Party, retired instead of running for re-election to a fifth term. Republican businesswoman Linda McMahon faced Democratic Representative Chris Murphy in the general election and lost, marking two defeats in as many years.


2012 United States Senate elections, Connecticut
In the 2006 election, incumbent Joe Lieberman was defeated in the Democratic primary by businessman Ned Lamont and formed his own party, Connecticut for Lieberman, winning re-election. Lieberman promised to remain in the Senate Democratic Caucus, but had clashed with Democrats on many significant issues, including his endorsement of Republican 2008 presidential nominee John McCain over Barack Obama. As a result, Lieberman's poll numbers among Democrats had dropped significantly.


2012 United States Senate elections, Connecticut
Connecticut Attorney General Richard Blumenthal was reportedly considering a run against Lieberman, but instead ran for and won Connecticut's other Senate seat in 2010 after U.S. senator Christopher Dodd announced his retirement.


2012 United States Senate elections, Connecticut
Lieberman had publicly floated the possibility of running as a Democrat, Republican, or an independent. However, he announced on January 19, 2011, that he would not run for another term.


2012 United States Senate elections, Connecticut
Susan Bysiewicz was the first to declare herself as a candidate. However, by March 2011 Chris Murphy had raised over $1 million, while Bysiewicz had raised only $500,000. Murphy represented Connecticut's 5th congressional district, which was considered Republican-leaning, and he promoted himself as the most electable candidate against a Republican challenger. Bysiewicz, the former Secretary of the State of Connecticut, enjoyed high name recognition while a statewide officeholder, and had a formidable face-off with Murphy. William Tong, a state representative, joined the race touting his biography as the son of Chinese immigrants working at a Chinese restaurant. In January East Hartford resident Matthew John Oakes announced his candidacy. Oakes pointed to his real life experience being a disabled American, victim of crime, civil rights activist, growing up in the inner-city and being a political outsider for his candidacy.


2012 United States Senate elections, Connecticut
Wide speculation continued on Linda McMahon, who had a widely publicized race for senator in 2010. She lost the election decisively, but had strong finances and a well-established political organization. McMahon met with her former campaign consultant to review her 2010 results, and said she was leaning towards running. She planned to make a decision regarding another run after the start of 2012. Congressman Chris Shays joined in August 2011, promoting his involvement in Iraq and Afghanistan's military contracting.


2012 United States Senate elections, Connecticut
Shays campaign also gained traction from a series of independent polls showing him beating or in dead heat with the top Democratic contenders in the general election, while those same polls showed McMahon losing handily to each of the top Democratic contenders. The Shays campaign has quickly capitalized on these polls, arguing for the former Congressman's electability while questioning McMahon's electability due to her loss in an open Senate seat contest in 2010 by a large margin despite spending $50 million of her own money, and also citing both her high unfavorable numbers among voters and her poor fundraising.


2012 United States Senate elections, Connecticut
In July 2012, Shays declared that he would not support McMahon if she won the primary. He said that he had "never run against an opponent that I have respected less—ever—and there are a lot of candidates I have run against," adding that "I do not believe that Linda McMahon has spent the time, the energy to determine what [being] a senator really means." He also said that during the last debate he had with McMahon, "I thought she was embarrassingly clueless" and that "I think she is a terrible candidate and I think she would make a terrible senator." Although he said he would not support Chris Murphy, he expected him to win the Democratic nomination and the general election.


2012 United States Senate elections, Connecticut
In September 2012, the records of the McMahons' 1976 bankruptcy and specifics of nearly $1 million unpaid debts from the proceeding were published. In days the candidate and her husband announced the "intention to reimburse all private individual creditors that can be located".

2012 United States Senate elections, Florida
The primary election was held August 14, 2012. Incumbent Democrat Bill Nelson won re-election to a third term, defeating Republican U.S. Representative Connie Mack IV by 13%, winning 55% to 42%. Nelson defeated Mack by over 1 million votes.


2012 United States Senate elections, Florida
From a long way out Nelson appeared to be vulnerable, with some earlier polls showing Mack leading. However, in the last few weeks with new polls conducted it appeared as though Nelson was headed for a victory. The last poll place him 5 percentage points ahead of Mack. In fact Nelson would win easily by 13 percentage points. Nelson performed well in Southeast Florida (the Miami area), Tampa, Gainesville, typically Democratic areas. Nelson however managed to win in areas that lean Republican. For example, Nelson won in Duval County home of Jacksonville, and Volusia County home of Daytona Beach. Nelson's ability to outperform President Obama led to him winning the Election easily. President Obama would still win Florida, but by just about 74,000 votes, and less than a percentage point. Nelson began his third term in the Senate on January 3, 2013.


2012 United States Senate elections, Hawaii
Incumbent Democrat Daniel Akaka retired instead of running for re-election to a fourth term. Democratic Congresswoman Mazie Hirono defeated former Hawaii Governor Linda Lingle in a rematch of the 2002 Hawaii gubernatorial election.


2012 United States Senate elections, Indiana
Incumbent Republican Richard Lugar ran for re-election to a seventh term, but was defeated in the primary by Tea Party-backed Richard Mourdock. Congressman Joe Donnelly, a moderate Democrat from Indiana's 2nd Congressional District, received his party's nomination after running unopposed in the primary contest, and then defeated both Mourdock and Libertarian Andrew Horning in the general election.


2012 United States Senate elections, Indiana
Due to Lugar's unpopularity among some Tea Party voters on his positions regarding illegal immigration, voting to confirm then-U.S. Supreme Court nominees Sonia Sotomayor and Elena Kagan, the DREAM Act, the START Treaty, some gun control bills, and congressional earmarks, he was challenged by a Tea Party-backed candidate.


2012 United States Senate elections, Indiana
The Indiana Debate Commission's GOP primary debate with Sen. Richard Lugar and State Treasurer Richard Mourdock was set to air at 7 p.m. EDT on Wednesday, April 11. In a widely published poll taken March 26 to 28, Lugar was still in the lead, but by the time of a second published poll from April 30 to May 1, Mourdock was leading 48% to 38% for Lugar.


2012 United States Senate elections, Indiana
Mourdock defeated senator Lugar in the Republican primary on May 8, 2012.


2012 United States Senate elections, Indiana
According to Indiana law, Lugar's defeat meant that he would not be permitted to run in the election either as a third party or an independent candidate after he lost the primary.

Mourdock became embroiled in a controversy after stating that pregnancy from rape is "something that God intended". His remarks were made during a debate on October 23, 2012, while explaining his opposition to abortion even in the case of rape. At the debate Mourdock, when asked what his position on abortion was, responded:


2012 United States Senate elections, Indiana
"I know there are some who disagree and I respect their point of view but I believe that life begins at conception. The only exception I have to have an abortion is in that case of the life of the mother. I just struggled with it myself for a long time but I came to realize: "Life is that gift from God that I think even if life begins in that horrible situation of rape, that it is something that God intended to happen"."


2012 United States Senate elections, Indiana
Media speculated that this could affect the outcome of the Senate race and Presidential race and multiple sources noted the similarities with the rape and pregnancy statement controversies in the 2012 United States elections.


2012 United States Senate elections, Indiana
Responding to the criticism, Mourdock issued a statement saying: "God creates life, and that was my point. God does not want rape, and by no means was I suggesting that he does. Rape is a horrible thing, and for anyone to twist my words otherwise is absurd and sick." He was later quoted at a press conference also saying: "I believe God controls the universe. I don't believe biology works in an uncontrolled fashion." He however refused to issue an apology, even while prominent Republicans, including Sen. John McCain, called for him to do so.


2012 United States Senate elections, Indiana
On election night Donnelly won by about six percent. Donnelly performed well in Marion County, home of Indianapolis. Donnelly also won areas with major college campuses, such as Indiana University in Bloomington, Purdue University in Lafayette. Mourdock performed well, as expected in the Indianapolis suburbs, such as Hamilton County. Mourdock conceded defeat to Donnelly at around 11:30 P.M. EST.


2012 United States Senate elections, Maine
Despite initially being in the race early on and poised to easily win, popular Republican Olympia Snowe suddenly retired instead of running for re-election to a fourth term. Former Independent Governor Angus King won the open seat. Following senator Joe Lieberman's retirement from the Senate in 2013, King became the second Independent incumbent senator, after Vermont's Bernie Sanders.


2012 United States Senate elections, Maine
Incumbent Olympia Snowe won re-election to a third term in 2006 with 74.01% of the vote over Democrat Jean Hay Bright and independent Bill Slavick. Due to the unpopularity of some of Snowe's votes among conservative voters, namely for the American Recovery and Reinvestment Act of 2009 and initial support of the Patient Protection and Affordable Care Act, there was speculation that she would face competition in the 2012 Republican primary from more conservative challengers. The Tea Party Express had promised to aid in a primary against Snowe. There had also been speculation that Snowe would switch parties, though she has always denied this. By June 2011, Snowe had officially entered her name with signatures to run in the Republican primary, saying, she "would never switch parties".


2012 United States Senate elections, Maine
However, on February 28, 2012, Snowe announced that she would be retiring from the U.S. Senate at the end of her term, citing the "atmosphere of polarization and 'my way or the highway' ideologies has become pervasive in campaigns and in our governing institutions" as the reason for her retirement. Her announcement opened the door for candidates from all parties and creating a much more contested 2012 election.


2012 United States Senate elections, Maryland
Incumbent Democrat Ben Cardin won re-election to a second term, defeating Republican nominee Dan Bongino and independent Rob Sobhani.


2012 United States Senate elections, Maryland

2012 United States Senate elections, Massachusetts
Incumbent Republican Scott Brown ran for re-election to a first full term. He had been elected in a special election in 2010 following the death of incumbent Democrat Ted Kennedy. Brown faced no challengers from his own party. For the Democrats, an initial wide field of prospective candidates narrowed after the entry of Harvard Law School Professor Elizabeth Warren, the architect of the Consumer Financial Protection Bureau. Warren clinched near-unanimous party support, with all but one of the other Democratic candidates withdrawing following her entrance. After winning her party's nomination, eliminating any need for a primary, she faced Brown in the general election.


2012 United States Senate elections, Massachusetts
The election was one of the most-followed races in 2012 and cost approximately $82 million, which made it the most expensive election in Massachusetts history and the second-most expensive in the entire 2012 election cycle, next to that year's presidential election. This was despite the two candidates' having agreed not to allow outside money to influence the race. Opinion polling indicated a close race for much of the campaign, though Warren opened up a small but consistent lead in the final few weeks. She went on to defeat Brown by over 236,000 votes, 54% to 46%.


2012 United States Senate elections, Massachusetts
Democratic U.S. senator Ted Kennedy was re-elected in 2006, and died on August 25, 2009, from a malignant brain tumor. On September 24, 2009, Massachusetts Governor Deval Patrick appointed longtime friend of Kennedy and former Democratic National Committee Chairman Paul G. Kirk to succeed Kennedy until a special election could be held. Kirk's appointment was especially controversial, as the Governor's ability to appoint an interim senator was removed during the Romney administration by the Democratic-controlled legislature, as a precaution if senator and presidential nominee John Kerry was elected President in 2004. Laws surrounding Senate appointment were quickly changed following Kennedy's death. The Massachusetts Republican Party sued in an attempt to halt Kirk's appointment, but it was rejected by Suffolk Superior Court Judge Thomas Connolly.


2012 United States Senate elections, Massachusetts
In the special election held January 19, 2010, Republican State senator Scott Brown defeated Democratic State Attorney General Martha Coakley in an upset victory. Brown thus became the first Republican to be elected from Massachusetts to the United States Senate since Edward Brooke in 1972 and he began serving the remainder of Kennedy's term on February 4, 2010.


2012 United States Senate elections, Massachusetts
Incumbent Scott Brown faced no challenges from within his party. The political action committee National Republican Trust, a group integral to Brown's election in 2010, vowed to draft a challenger for Brown but were unable to find one.

The Massachusetts Democratic Convention was held June 2, 2012, where Warren received 95.77% of delegate votes. As the only candidate with 15% of delegate votes necessary to qualify for the primary ballot, Warren eliminated her challenger Marisa DeFranco, becoming the de facto nominee. The Democratic primary was held September 6, 2012, with Warren running unopposed.


2012 United States Senate elections, Massachusetts
Brown ran as a moderate, stressing his ability to cross party lines and highlighting his votes for the Dodd-Frank financial reform law and to repeal "don't ask, don't tell". Warren campaigned on a platform championing the middle class, and supporting Wall Street regulation. Warren criticized Brown for continually voting with Republican leadership, and argued that he was not the bipartisan moderate he claimed to be. A staple of Brown's attack tactics against Warren was his consistent reference to her as "Professor Warren", in attempt to portray her as an elitist academic. Brown faced blowback after the second debate, during which he claimed conservative Antonin Scalia was a "model" Supreme Court Justice, prompting boos from the debate audience.


2012 United States Senate elections, Massachusetts
Warren spoke at the 2012 Democratic National Convention immediately before Bill Clinton on the penultimate night of the convention. Warren contrasted President Obama's economic plan with Mitt Romney's in the 2012 election and rebuked the Republican Party's economic policy stating: "Their vision is clear: 'I've got mine, and the rest of you are on your own.'" Warren positioned herself as a champion of a beleaguered middle class that, as she said, "has been chipped, squeezed and hammered." Brown attended the 2012 Republican National Convention, but was not a speaker there. According to Brown, he had rejected an offer to play a larger role, and limited his attendance to a single day because of scheduling demands.


2012 United States Senate elections, Massachusetts
Following Todd Akin's controversial "legitimate rape" comments, Brown was the first sitting senator to demand he drop out of the Missouri U.S. Senate race. He also called on his Party to "recognize in its platform that you can be pro-choice and still be a good Republican." Brown's campaign had been endorsed by many Massachusetts Democrats, many of whom were prominently featured in his campaign ads.


2012 United States Senate elections, Massachusetts
In September 2011, a video of Warren explaining her approach to economic policy gained popularity on the internet. In the video, Warren rebuts the charge that asking the rich to pay more taxes is "class warfare", pointing out that no one grew rich in America without depending on infrastructure paid for by the rest of society, stating:


2012 United States Senate elections, Massachusetts
There is nobody in this country who got rich on his own. Nobody. ... You moved your goods to market on the roads the rest of us paid for; you hired workers the rest of us paid to educate; you were safe in your factory because of police forces and fire forces that the rest of us paid for. You didn't have to worry that marauding bands would come and seize everything at your factory, and hire someone to protect against this, because of the work the rest of us did. Now look, you built a factory and it turned into something terrific, or a great idea. God bless. Keep a big hunk of it. But part of the underlying social contract is, you take a hunk of that and pay forward for the next kid who comes along.


2012 United States Senate elections, Massachusetts
On July 13, 2012, President Obama sparked a controversy when he echoed her thoughts in a campaign speech saying, "Somebody helped to create this unbelievable American system that we have that allowed you to thrive. Somebody invested in roads and bridges. If you've got a business—you didn't build that. Somebody else made that happen."


2012 United States Senate elections, Massachusetts
Warren encountered significant opposition from business interests. In August 2012, Rob Engstrom, political director for the United States Chamber of Commerce, claimed that "no other candidate in 2012 represents a greater threat to free enterprise than Professor Warren." She nonetheless raised $39 million for her campaign, the most of any Senate candidate in 2012.


2012 United States Senate elections, Massachusetts
Despite President Obama's winning the state easily, and winning all of the state's counties, this race was fairly close. As expected, Warren performed very well in Suffolk County, which is home to the state's largest city and its capital Boston. Brown performed well in the southern part of the state near Cape Cod. Warren made history by becoming the first woman elected to the U.S. Senate in the state of Massachusetts.


2012 United States Senate elections, Michigan
Incumbent Democrat Debbie Stabenow was re-elected to a third term after being unopposed in the Democratic primary. The Republican nominee was former Congressman Pete Hoekstra. Stabenow defeated Hoekstra by a landslide 21% margin and by almost one million votes.


2012 United States Senate elections, Michigan
The GOP primary campaign was mainly a battle between Hoekstra and Durant as they were the most visible in running campaign ads. Despite Durant's attack ads, Hoekstra was leading in the polls for the Republican nomination.


2012 United States Senate elections, Minnesota
Incumbent Democrat Amy Klobuchar was re-elected to a second term in a landslide, defeating the Republican nominee, State Representative Kurt Bills by almost one million votes, and carrying all but two of the state's counties.


2012 United States Senate elections, Minnesota
Incumbent Amy Klobuchar was first elected in 2006 to succeed the retiring DFL incumbent Mark Dayton.


2012 United States Senate elections, Minnesota
The Independence Party of Minnesota did not plan to run a candidate in the general election. Party chairman Mark Jenkins said in November 2011 that he saw the Senate election as "a distraction from having our best and brightest engaged in state legislative races". At the party's convention in June 2012, neither candidate was endorsed although Williams won a majority of the votes and came within two votes of the required 60% needed for the party's endorsement. He proceeded with his run for the Senate but the party focused its attention on state legislative races.


2012 United States Senate elections, Mississippi
Incumbent Republican Roger Wicker won re-election to his first full term over Democrat Albert N. Gore. Former U.S. representative Roger Wicker was appointed by Governor Haley Barbour after then-incumbent Trent Lott retired at the end of 2007. A 2008 special election was later scheduled to determine who would serve the remainder of the term. Then-U.S. Sen. Roger Wicker defeated former Mississippi Governor Ronnie Musgrove with 54.96% of the vote in the special election and will be up for re-election in 2012. This would've been Trent Lott's fifth term as senator had he remained in office.


2012 United States Senate elections, Missouri
Incumbent Democrat Claire McCaskill was unopposed in her primary and U.S. Representative Todd Akin won the Republican nomination with a plurality in a close three-way race. McCaskill was re-elected to a second term.


2012 United States Senate elections, Missouri
Time featured the race in their Senate article. Similar to other races, the article mentioned how McCaskill was fading in pre-election polls, and she was considered the most vulnerable/endangered Democratic incumbent that year. But Akin's comments about a woman's body preventing pregnancy if it was "legitimate rape" quickly shot McCaskill back up, winning her the election.


2012 United States Senate elections, Missouri
The Republican primary, held August 7, 2012, was one of the three most anticipated of summer 2012. This was due to the projected closeness of the Federal races in the 'Show-Me State' in November 2012, and the potential to change the control of the Senate in January 2013. Democrats believed that Todd Akin would be the weakest among the likely challengers for the Senate seat, and ads attacking him as "too conservative" were largely viewed as a veiled support for his nomination.


2012 United States Senate elections, Missouri
While making remarks on rape and abortion on August 19, 2012, Akin made the claim that women victims of what he described as "legitimate rape" rarely experience pregnancy from rape. In an interview aired on St. Louis television station KTVI-TV, Aiken was asked his views on whether women who became pregnant due to rape should have the option of abortion. He replied:


2012 United States Senate elections, Missouri
Well you know, people always want to try to make that as one of those things, well how do you, how do you slice this particularly tough sort of ethical question. First of all, from what I understand from doctors, that's really rare. If it's a legitimate rape, the female body has ways to try to shut that whole thing down. But let's assume that maybe that didn't work or something. I think there should be some punishment, but the punishment ought to be on the rapist and not attacking the child.


2012 United States Senate elections, Missouri
The comments from Akin almost immediately led to uproar, with the term "legitimate rape" being taken to imply belief in a view that some kinds of rape are "legitimate", or alternatively that the many victims who do become pregnant from rape are likely to be lying about their claim. His claims about the likelihood of pregnancy resulting from rape were widely seen as being based on long-discredited pseudoscience with experts seeing the claims as lacking any basis of medical validity. Akin was not the first to make such claims, but was perhaps one of the most prominent.


2012 United States Senate elections, Missouri
While some voices such as Iowa congressman Steve King supported Akin, senior figures in both parties condemned his remarks and some Republicans called for him to resign. In the resulting furor, Akin received widespread calls to drop out of his Senate race from both Republicans and Democrats. Akin apologized after making the comment, saying he "misspoke", and he stated he planned to remain in the Senate race. This response was itself attacked by many commentators who saw the initial comments as representative of his long-held views, rather than an accidental gaffe.


2012 United States Senate elections, Missouri
The comment was widely characterized as misogynistic and recklessly inaccurate, with many commentators remarking on the use of the words "legitimate rape". Related news articles cited a 1996 article in an obstetrics and gynecology journal, which found that 5% of women who were raped became pregnant, which equaled about 32,000 pregnancies each year in the US alone. A separate 2003 article in the journal Human Nature estimated that rapes are twice as likely to result in pregnancies as consensual sex. (See also pregnancy from rape.)


2012 United States Senate elections, Missouri
The incident was seen as having an impact on Akin's senate race and the Republicans' chances of gaining a majority in the U.S. Senate, by making news in the week before the 2012 Republican National Convention and by "shift[ing] the national discussion to divisive social issues that could repel swing voters rather than economic issues that could attract them". Akin, along with other Republican candidates with controversial positions on rape, lost due to backlash from women voters.


2012 United States Senate elections, Missouri
On October 20, at a fundraiser, Akin compared McCaskill to a dog. After being criticized, Akin's campaign aide wrote on his official Twitter page that if Claire McCaskill "were a dog, she'd be a ‘Bullshitsu.’" The aide later said that he was joking. Akin was caught on tape commenting that "Sen. Claire McCaskill goes to Washington, D.C., to 'fetch' higher taxes and regulations."


2012 United States Senate elections, Missouri
Even though the last poll before the election showed Akin only losing by four percentage points, McCaskill defeated him handily, by a 15.5% margin of victory and a vote margin of 420,985. Both McCaskill and incumbent Governor Jay Nixon, running at the same time, were able to get a large number of votes from rural parts of the state, something President Barack Obama was not able to do. McCaskill and Nixon were declared the winners of their respective races even before the known big Democratic strongholds of St. Louis and Kansas City came in. Akin conceded defeat to McCaskill at 10:38 P.M. Central Time.

2012 United States Senate elections, Montana
Incumbent Democrat Jon Tester successfully ran for re-election to a second term.


2012 United States Senate elections, Montana
Former president of the Montana Senate and farmer Jon Tester was elected with 49.2% of the vote in 2006, defeating incumbent Conrad Burns.


2012 United States Senate elections, Montana
As of June 30, 2011, Jon Tester had saved $2.34 million in campaign funds. Tester has been accused by Republican Denny Rehberg's senate campaign of depending on financial contributions from Wall Street banking executives and movie stars.


2012 United States Senate elections, Montana
On February 5, 2011, U.S. Representative Denny Rehberg announced his intention to run for the U.S. Senate. Steve Daines had announced he would seek the Republican nomination on November 13, 2010, but just before Rehberg's announcement he dropped out of the primary and announced he would instead seek the Republican nomination for Montana's at-large congressional district in 2012.


2012 United States Senate elections, Montana
As of early July 2010, Denny Rehberg had saved $1.5 million of an original $2 million in campaign funds. Rehberg accused Democrat Jon Tester's senate campaign of depending on financial contributions from Wall Street banking executives and Hollywood while Rehberg's campaign relies primarily on in state donations. Tester's campaign countered that Rehberg has been funded by petroleum special interests and Wall Street.


2012 United States Senate elections, Montana
The National Republican Senatorial Committee aired an attack ad against Jon Tester that mistakenly included a digitally manipulated photo of Tester (who has only two fingers on his left hand) with full sets of fingers. Another ad against Tester, from the Karl Rove group Crossroads GPS, falsely asserted that Tester had voted in favor of Environmental Protection Agency regulation of farm dust. In fact, Tester had praised the EPA for not attempting such a regulation. The vote cited in the anti-Tester ad concerned currency exchange rates.


2012 United States Senate elections, Montana
In early October 2012, Crossroads GPS announced it would launch a $16 million advertising buy in national races, of which four were this and three other Senate elections.

2012 United States Senate elections, Nevada
Incumbent Republican Dean Heller, who was recently appointed to this seat left vacant by resigning U.S. senator John Ensign, was narrowly elected to his first full term over Congresswoman Shelley Berkley.


2012 United States Senate elections, Nevada
Ensign had been re-elected in 2006 over Jack Carter, son of former president Jimmy Carter, by a margin of 55–41%. Ensign's re-election campaign was expected to be complicated after it was revealed in 2009 that he had been involved in an extramarital affair with the wife of one of his campaign staffers, allegedly made payments to the woman's family and arranged work for her husband to cover himself.


2012 United States Senate elections, Nevada
Ensign faced an investigation from the Senate Ethics Committee and his poll numbers declined significantly. There was speculation that Ensign might resign before the election, but he denied these charges and initially stated he would run. However, he changed his mind and on March 7, 2011, Ensign announced that he would not seek re-election. On April 22, Ensign announced that he was resigning effective May 3. This is the only senate election in 2012 to vote Republican while Obama carried it on the presidential level.


2012 United States Senate elections, New Jersey
Incumbent Democrat Bob Menendez won re-election to a second full term. This was the first time since 1976 that a candidate for this seat received over 55% of the vote. Bob Menendez became the first Hispanic-American U.S. senator to represent New Jersey in January 2006 when former U.S. senator Jon Corzine appointed him to the seat after having resigned to become governor of New Jersey, following his election in November 2005. In November 2006, after a tough and painful election, Menendez defeated Republican state senator Thomas Kean, Jr. with 53.3% of the vote.


2012 United States Senate elections, New Mexico
Incumbent Democrat Jeff Bingaman retired instead of running for re-election to a sixth term. Democratic U.S. Representative Martin Heinrich won the open seat. Incumbent Jeff Bingaman won re-election to a fifth term with 70.61% of the vote against Allen McCulloch in the 2006 U.S. senatorial election in New Mexico.


2012 United States Senate elections, New York
Incumbent Democrat Kirsten Gillibrand won re-election to her first full term. Gillibrand was opposed in the general election by Wendy Long (who ran on the Republican and Conservative Party tickets) and by three minor party candidates. Gillibrand was re-elected with 72% of the vote, by a margin of 46%, the highest margin for any statewide candidate in New York. Gillibrand performed 9 points better than President Barack Obama did in the presidential race in New York. She carried 60 out of 62 counties statewide. There was one debate, held in October 2012 where Gillibrand and Long debated various issues such as the economy, abortion rights, the debt and deficit, foreign policy, jobs, and tax and regulatory policy.


2012 United States Senate elections, New York
Governor David Paterson appointed then-U.S. Representative Kirsten Gillibrand to serve as U.S. senator from New York until the 2010 special election, succeeding former U.S. senator Hillary Clinton, who resigned to serve as U.S. Secretary of State in the Obama administration. Gillibrand won the special election in 2010 with 62.95% of the vote over former U.S. Representative Joseph DioGuardi.


2012 United States Senate elections, New York
According to preliminary results, Gillibrand won re-election by a landslide of over 70% of the vote on November 6, 2012.


2012 United States Senate elections, North Dakota
Incumbent Democrat Kent Conrad retired instead of running for re-election to a fifth term. Though each party endorses a single candidate in state political conventions in the spring, North Dakota determines actual ballot access for the general election in a statewide primary election that was held June 12, 2012. Former Democratic-NPL Attorney General Heidi Heitkamp ran for and won the open seat in a close-fought victory.


2012 United States Senate elections, Ohio
Incumbent Democrat Sherrod Brown won re-election to a second term. He was unopposed in the Democratic primary and Ohio State Treasurer Josh Mandel won the Republican primary with 63% of the vote.


2012 United States Senate elections, Ohio
In 2006, U.S. Representative Sherrod Brown had defeated two-term incumbent Republican Mike DeWine 56%-44% 2006 election. Over the past six years, he established a very liberal, progressive, and populist record. The National Journal named Brown the most liberal U.S. senator in the past two years. The Washington Post called him a "modern-day Paul Wellstone." One article said "Brown is way to the left of Ohio in general, but probably the only person who could outwork Brown is Portman." Brown was the only candidate the 60 Plus Association targeted in the 2012 election cycle.


2012 United States Senate elections, Ohio
Mandel, 34, was elected state treasurer in 2010. Before that, he was a Lyndhurst City Councilman and Ohio State Representative. He was criticized as Ohio Treasurer for not fulfilling his pledge to serve a four-year term and for not attending any of the Board of Deposit monthly meetings. However, Mandel raised a lot of money. He was called a rising star in the Republican Party and was called "the rock star of the party." He was also compared to Marco Rubio.


2012 United States Senate elections, Ohio
Mandel's campaign was singled out by the independent fact-checking group Politifact for its "casual relationship with the truth" and its tendency to "double down" after inaccuracies were pointed out. The fact-checking group wrote: "For all the gifts Mandel has, from his compelling personal narrative as an Iraq war veteran to a well-oiled fundraising machine, whoppers are fast becoming a calling card of his candidacy."


2012 United States Senate elections, Ohio
Mandel raised $7.2 million through the first quarter of 2012. He had $5.3 million cash on hand, trailing Brown's $6.3 million. However, Mandel benefited from massive support from conservative out-of-state superPACs, which raise unlimited amounts of money from anonymous donors. These outside groups, including Crossroads GPS, aired over $60 million in TV advertising supporting Mandel and attacking Brown, outspending Democratically aligned outside groups by more than five-to-one. Mandel's campaign was aided by over $1 million spent primarily on attack ads by a 501(c)(4) organization called the Government Integrity Fund. The group was funded by anonymous donors and run by lobbyist Tom Norris of Columbus, Ohio-based Cap Square Solutions.


2012 United States Senate elections, Ohio
Brown did better than polls right before the election suggested. Instead of winning by two points (which polls right before the election had suggested) Brown won by six points. Republicans could not come back from the huge margins for the Democrats of Cuyahoga County, Franklin County, Lucas County, and Hamilton County.


2012 United States Senate elections, Pennsylvania
Incumbent Democrat Bob Casey, Jr. won re-election to a second term, defeating Republican nominee Tom Smith, and Libertarian nominee Rayburn Smith.


2012 United States Senate elections, Pennsylvania
The primary elections occurred on April 24, 2012, during which the Republicans and Democrats selected nominees for the general election. The Republican primary was a five-way contest. Tom Smith, the eventual nominee, faced David A. Christian, Sam Rohrer, Marc Scaringi, and Steve Welch. The Democratic primary was not heavily contested. Incumbent Bob Casey, Jr., defeated Joseph Vodvarka by a wide margin. The Libertarian Party nominated Rayburn Smith.


2012 United States Senate elections, Pennsylvania
Casey led most pre-election polls and eventually defeated his opponents to win re-election to a second term in the U.S. Senate. In so doing, Casey became the first Democratic senator from Pennsylvania elected to a second term in 50 years.


2012 United States Senate elections, Pennsylvania
Pennsylvania was considered a battleground state; since the 1970 election of Governor Milton Shapp, partisan control of the governorship had alternated between Democratic and Republican. Additionally, Republicans had controlled the State Senate since 1995, while Democrats assumed control of the State House following the 2006 election, only to lose control in the 2010 election, though the Democrats had won the state in every presidential election from 1992 to 2012.


2012 United States Senate elections, Pennsylvania
Despite many predictions of a close race, the election was not close. Casey, the incumbent, despite being seen as somewhat vulnerable, went into election night with most analysts thinking he would win. Casey would win by more than expected. This can be traced to several factors. Casey trounced Smith in Philadelphia County home of Philadelphia. Casey also won the surrounding collar counties of, Bucks, Chester, Delaware, and Montgomery, which are seen as vital in statewide elections in Pennsylvania. Casey also performed well in Allegheny County home of Pittsburgh. Casey also performed well in Erie. Casey also performed strongly in the Scranton area. Smith did well in rural counties, but it wasn't enough to overcome the lead Casey had built in the huge population centers. Casey was sworn in for his second term beginning at noon on January 3, 2013.


2012 United States Senate elections, Rhode Island
Incumbent Democrat Sheldon Whitehouse was re-elected to a second term in a landslide by a 30% margin of 65% - 35%. Whitehouse won 53.52% of the vote in 2006.


2012 United States Senate elections, Tennessee
Incumbent Republican Bob Corker won a second term. Corker easily won the Republican primary with 85% of the vote. He faced Democratic Party nominee Mark E. Clayton as well as several third-party candidates and several independents.


2012 United States Senate elections, Tennessee
Clayton won the Democratic nomination with 30% of the vote, despite raising no money and having a website that was four years out of date. The next day Tennessee's Democratic Party disavowed the candidate over his active role in the Public Advocate of the United States, which they described as a "known hate group".


2012 United States Senate elections, Tennessee
They blamed his victory among candidates for whom the TNDP provided little forums to become known on the fact that his name appeared first on the ballot, and said they would do nothing to help his campaign, urging Democrats to vote for "the write-in candidate of their choice" in November.


2012 United States Senate elections, Tennessee
One of the Democratic candidates, Larry Crim, filed a petition seeking to offer the voters a new primary in which to select a Democratic Nominee among the remaining candidates the party had affirmed as bona fide and as a preliminary motion sought a temporary restraining order against certification of the results, but after a judge denied the temporary order Crim withdrew his petition


2012 United States Senate elections, Texas
Incumbent Republican Kay Bailey Hutchison retired instead of running for re-election to a fourth full term. Libertarian John Jay Myers was elected by nomination at the Texas Libertarian Party State Convention on June 8, 2012. After the first round of primary on May 29, 2012, a runoff was held July 31, 2012, for both the Democratic and Republican parties, with Paul Sadler and Ted Cruz winning, respectively. Cruz won the open seat.


2012 United States Senate elections, Utah
Incumbent Republican Orrin Hatch won re-election to a seventh term against former state senator and IBM executive, Scott Howell the Democratic candidate.


2012 United States Senate elections, Utah
In 2006, incumbent Orrin Hatch won re-election to a sixth term. In 2008, Jason Chaffetz defeated the incumbent Republican U.S. Representative, Chris Cannon, in the 2008 primary for Utah's 3rd congressional district. In 2010, Mike Lee defeated Bob Bennett in the 2010 Utah Senate election. In March 2011, just-elected U.S. senator Mike Lee said he will not endorse Hatch in the primary. In May 2011, Chaffetz told several Utah political insiders that he planned to run, but he would not make an official decision until after Labor Day of 2011.


2012 United States Senate elections, Utah
In June 2011, prominent conservative radio talk show host Mark Levin endorsed Hatch. The fiscally conservative 501(c)4 organization Club for Growth encouraged Chaffetz to run. The group cited Hatch's support for the Troubled Asset Relief Program, State Children's Health Insurance Program, No Child Left Behind Act, Bridge to Nowhere, and other votes among the reasons why they opposed his re-election. In an interview with Politico, Chaffetz stated, "After 34 years of service, I think most Utahans want a change. They want to thank him for his service, but it's time to move on. And for me personally, I think he's been on the wrong side of a host of major issues." The congressman cited Hatch's vote in favor of Equal Opportunity to Serve Act and the Health Equity and Access Reform Today Act of 1993. However, Chaffetz ultimately decided against a run.

2012 United States Senate elections, Virginia
Incumbent Democrat Jim Webb retired instead of running for re-election to a second term. Former Governor of Virginia Tim Kaine was unopposed for the Democratic nomination and the Republican party nominated former senator and Governor George Allen through a primary on June 12, 2012. Kaine won the open seat.


2012 United States Senate elections, Virginia
Once Democrat Jim Webb retired, many Democratic candidates were speculated. These included U.S. Congressmen Rick Boucher, Gerry Connolly, Glenn Nye, Tom Perriello and Bobby Scott. However, they all declined and encouraged Kaine to run for the seat, believing he would be by far the most electable candidate. Courtney Lynch, former Marine Corps Officer and Fairfax business consultant and Julien Modica, former CEO of the Brain Trauma Recovery & Policy Institute, eventually withdrew from the election, allowing Kaine to be unopposed in the Democratic primary.
