2018 United States Senate election in Arizona
The 2018 United States Senate election in Arizona took place on November 6, 2018, to elect a member of the United States Senate to represent the State of Arizona and replace incumbent Republican Senator Jeff Flake, who did not run for reelection to a second term. It was held concurrently with a gubernatorial election, other elections to the U.S. Senate, elections to the U.S. House of Representatives, as well as various other state and local elections.


2018 United States Senate election in Arizona
The candidate filing deadline was May 30, 2018; primaries were held on August 28, 2018, three days after the death of Senator John McCain. Martha McSally won the Republican nomination, while Kyrsten Sinema won the Democratic nomination. Green Party candidate Angela Green was also on the ballot but had withdrawn and endorsed Sinema. The election thus featured an all-female ballot. Write-in candidates included Democrat Sheila Bilyeu, Libertarian Party candidate Barry Hess, Republican Robert Kay, Jonathan Ringham of The Old Republic, as well as others. On the night of the election, McSally held a narrow lead of about one percent.


2018 United States Senate election in Arizona
Approximately a million mail-in and early ballots however remained to be counted; Sinema took the lead the next day, in a blue shift. The Associated Press called the race for Sinema on November 12, 2018 and McSally conceded that day. With a margin of 2.34%, this election was the second-closest race of the 2018 U.S. Senate election cycle, behind only the Senate election in Florida.


2018 United States Senate election in Arizona
Sinema became the first Democrat to win a U.S. Senate seat in Arizona since 1988 when former Democratic Senator Dennis DeConcini last ran for and won reelection to his third and final term in this seat. McSally was subsequently appointed by Governor Doug Ducey to the other vacant Senate seat in Arizona, left open after McCain's death and then held on an interim basis by Jon Kyl. Two years later, McSally attempted to defend her seat in the 2020 special election and serve the remainder of the term, but lost to Democrat Mark Kelly.


2018 United States Senate election in Arizona, Background
Arizona, located along the United States border with Mexico, has a unique political history. Upon its admission to the Union in 1912, the state was dominated by Democrats who had migrated there from the South, and aside from the landslide victories of Republicans Warren G. Harding, Calvin Coolidge, and Herbert Hoover, the state voted for Democrats until 1952, when Dwight Eisenhower carried it, and began a lengthy streak of Republican victories interrupted only by Bill Clinton's narrow victory in 1996.


2018 United States Senate election in Arizona, Background
Since then, the state had remained in the Republican camp, and was won by Donald Trump with a 3.5% margin in 2016, although Trump's margin of victory was much smaller than that of past Republican presidential nominees. The last Democrat to win a Senate election in Arizona was Dennis DeConcini in 1988.


2018 United States Senate election in Arizona, Background
Incumbent Republican Senator Jeff Flake announced in October 2017 that he would retire at the end of his current term instead of seeking reelection for another term in 2018. Flake had previously indicated his intent to run for reelection in March 2017. However, he was considered vulnerable due to persistently low approval ratings, a poor relationship with President Trump, and the threat of a primary challenge from former State Senator Kelli Ward, who promised to run on a more pro-Trump platform. Additionally, he had won his first term in 2012 by only 3 percentage points, even though Republican presidential nominee Mitt Romney won Arizona by 9.


2018 United States Senate election in Arizona, Results
Due to the closeness of the vote count, the Associated Press and other major news outlets did not call the race until November 12, 2018, six days after the election.


2018 United States Senate election in Arizona, Results
Sinema defeated McSally largely by winning in heavily populated Maricopa County, home of Phoenix, which used to be a Republican stronghold but has since trended more Democratic in recent years. Sinema also won in heavily populated Pima County, home to Tucson, where she beat McSally with over 56% of the vote. Sinema also performed well in Coconino County, home of Flagstaff. McSally did well in many rural areas of the state. This was the first Senate election won by a Democrat in Arizona since 1988.


2018 United States Senate election in Arizona, Aftermath
On December 18, 2018, Governor Doug Ducey appointed McSally to fill Arizona's other Senate seat, left vacant after the resignation of Jon Kyl, who himself was appointed after the August 25, 2018 death of John McCain. Initially, Kyl said that he would serve only until the new Congress was sworn in January 2019.


2018 United States Senate election in Arizona, Aftermath
Both Sinema and McSally were sworn in with the 116th United States Congress on January 3, 2019, marking the first time in history that Arizona was represented by two women in the United States Senate and making it the second state to be represented by two women from different parties. Sinema and McSally are only the second pair of senators from the same state in history to serve together after running against each other the prior year; a first such instance occurred in Oregon in 1996–1997.


2018 United States Senate election in Arizona, Aftermath
Ducey stipulated that Sinema would be sworn in first, making her the senior senator; this way, he said, the decision of Arizona's voters would be respected. Under Arizona law, McSally's appointment was only valid for the duration of the 116th Congress and a special election for her seat was held in November 2020 to determine who would finish what remains of McCain's term (which expires in 2023), in which McSally was defeated by Democrat Mark Kelly. McSally left office on December 2, 2020.


2018 United States Senate election in California
The 2018 United States Senate election in California took place on November 6, 2018, to elect a member of the United States Senate to represent California, concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections.


2018 United States Senate election in California
Under California's non-partisan blanket primary law, all candidates appear on the same ballot, regardless of party. In the primary, voters may vote for any candidate, regardless of their party affiliation. In the California system, the top two finishers—regardless of party—advance to the general election in November, even if a candidate receives a majority of the votes cast in the primary election. Washington and Louisiana have similar "jungle primary" style processes for U.S. Senate elections, as does Mississippi for U.S. Senate special elections.


2018 United States Senate election in California
The candidate filing deadline was March 8, 2018 and the primary election was held on June 5, 2018.


2018 United States Senate election in California
Four-term Democratic incumbent Dianne Feinstein won reelection in 2012 with 63% of the vote, taking the record for the most popular votes in any U.S. Senate election in history with 7.86 million votes. Feinstein at the time was the ranking member of the Senate Judiciary Committee. She turned 85 years old in 2018, leading some to speculate that she would retire in January 2019, as her long-time colleague Barbara Boxer did in January 2017.


2018 United States Senate election in California
However, Feinstein stood for reelection for her fifth consecutive term, winning 44.2% of the vote in the top-two primary; she faced Democratic challenger Kevin De León in the general election, who won 12.1% of the primary vote. For the second time since direct elections to the Senate began after the passage of the Seventeenth Amendment in 1913, no Republican appeared on the general election ballot for U.S. Senate in California. The highest Republican finisher in the primary won only 8.3 percent of the vote, and the 10 Republicans only won 31.2 percent of the vote among them.


2018 United States Senate election in California
In the general election, Feinstein defeated De León by an eight-point margin, 54% to 46%.


2018 United States Senate election in California, Primary election, Results
Democratic candidates won a combined total of 4,231,444, Republican candidates 2,216,223 votes, and other candidates 223,053 votes.


2018 United States Senate election in California, General election, Predictions
Because of California's top-two runoff system, the seat was guaranteed to be won/held by a Democrat since the initial primary produced two Democratic candidates.


2018 United States Senate election in California, General election, Results
The race had an undervote of around 1.3 million votes compared to the gubernatorial election, likely by Republican voters choosing neither candidate. De León won many of the same counties and congressional districts won by Republican gubernatorial nominee John Cox, as many voters may have expressed opposition to the incumbent senator. No county voted for both Feinstein and Cox. Congressional districts 39, 45, and 48 were the only congressional districts that voted for both Feinstein and Cox.


2018 United States Senate election in California, General election, Results by county
Results by county. Blue represents counties won by Feinstein. Yellow represents counties won by de León.

Carper was not present because of the U.S. Senate's extended session due to session ceasing early the Thursday prior because of the death of former Governor and U.S. Senator of Nevada, Paul Laxalt. Arlett declined and claimed he had a scheduling conflict.

2018 United States Senate election in Florida
The 2018 United States Senate election in Florida was held on November 6, 2018, alongside a gubernatorial election, elections to the U.S. House of Representatives and other state and local elections. Incumbent Democratic Senator Bill Nelson ran for re-election to a fourth term, but was narrowly defeated by Republican Governor Rick Scott. This was the closest Senate race in the state's history.


2018 United States Senate election in Florida
The results of the race were in dispute for 12 days following the election. The results showed that Nelson was narrowly trailing Scott, but the margin remained below 0.5%, triggering an automatic recount under Florida law. A controversial recount ensued, with both campaigns claiming irregularities. Following the recount, Florida elections officials confirmed Scott's victory on November 18, 2018. Scott received 50.05% of the vote, while Nelson received 49.93%; the margin of victory was 10,033 votes out of 8.19 million votes cast, or 0.12%. Both in terms of raw vote margin and by percentage of difference, this was the closest Senate election in the 2018 cycle. Scott's victory marks the first time since the Reconstruction era that Republicans have held both Senate seats in Florida.


2018 United States Senate election in Florida, Background
As of the second quarter of 2018, incumbent Democratic Senator Bill Nelson had a 44%-34% approval rating among his constituents. Republican former President Donald Trump also held a positive approval rating of 49%-47% in Florida as of August 2018. Trump won the state in 2016 by 1.2% over Democratic nominee Hillary Clinton. Nelson was challenged by term-limited Governor Rick Scott, who put more than $86 million of his own money into his successful 2010 and 2014 gubernatorial bids.


2018 United States Senate election in Florida, Background
Despite having won re-election in 2012 by a 13% margin, Nelson was considered potentially vulnerable; he had been the only statewide elected Democrat in Florida since 2011, and his previous opponents, Connie Mack IV and Katherine Harris, were seen as much weaker challengers than Scott. Additionally, he was one of 10 incumbent Democratic Senators running in a state that had been carried by President Trump in 2016. Nelson was described as a —"low-key centrist" that might not be able to energize progressive voters.


2018 United States Senate election in Florida, Background
After being encouraged by President Trump to enter the Senate race, Scott announced his candidacy on April 9, 2018, weeks after the end of his final regular legislative session as governor. During the campaign, Scott sought to avoid mentioning President Trump and at times criticized or distanced himself from actions of the Trump administration, whereas in the past he used his friendship with Trump to boost his profile and had been an early and vocal supporter of Trump in 2016  and was reported to speak to President Trump every one or two weeks by The Tampa Bay Times. Nevertheless, Trump endorsed Scott in his Senate bid. As of the first quarter of 2018, Scott held a 54%-35% approval rating among his constituents, with a majority of Florida voters believing the state was moving in the right direction under Scott's administration.


2018 United States Senate election in Florida, Background
Both–Nelson's and Scott's–responses to Hurricanes Irma and Michael, which made landfall in September 2017 and October 2018 respectively, were closely watched during the campaign season.


2018 United States Senate election in Florida, Republican primary
The Republican primary was considered merely a formality, as Governor Scott's lone challenger was a perennial candidate who was running for Senate seats in eight other Republican primaries across the country. No other notable Republicans entered the race before or after Scott announced his candidacy.


2018 United States Senate election in Florida, Democratic primary
As both of Senator Nelson's primary opponents failed to qualify for the ballot, no Democratic primary was held.


2018 United States Senate election in Florida, General election
The election was expected to be a key race in determining which party would control the U.S. Senate in 2019. According to The Cook Political Report, the race was one of the 10 most competitive U.S. Senate races in the nation. It was also described as the most expensive U.S. Senate race in the country.


2018 United States Senate election in Florida, General election
Scott's involvement in a large Medicare fraud case stirred controversy during the general election campaign. Scott responded with ads accusing Nelson of having cut Medicare benefits and stolen from Medicare; fact-checkers found that both of Scott's assertions were "mostly false." During the campaign, Scott characterize[s] Nelson as a "socialist"; PolitiFact described the assertion as "pants-on-fire" false.


2018 United States Senate election in Florida, General election
Gun control was a key issue in this race. The election comes less than nine months after the Stoneman Douglas High School shooting in Parkland, the deadliest school shooting in American history. Nelson also mentioned the Orlando nightclub shooting that occurred in June 2016 and killed 49 people, stating that —"nothing was done" by Scott's administration. In the wake of Stoneman Douglas, Scott raised the age to purchase a gun from 18 to 21, set a three-day waiting period to purchase assault-style weapons, and banned bump stocks, moves that Nelson[he] described as [him] "doing the bare ...minimum[s]." The National Rifle Association opposed Scott's legislation.


2018 United States Senate election in Florida, General election
Environmental issues also took on a prominent role in the race. Scott and his administration had been heavily criticized for weakening regulations designed to protect the environment, even going as far as to instruct the FDEP not to use the words "climate change" or "global warming" in official reports. Because of this, Scott was blamed for the state's worsening algae blooms, even being dubbed "Red Tide Rick" on social media. Scott blamed the toxic blooms on Nelson and on Congress' general inefficiency.


2018 United States Senate election in Florida, General election, Initial results and recount
The results of the race were in dispute for 12 days following the election. Because Scott's lead over Nelson was less than 0.5% of the vote, an automatic recount was triggered under Florida law. A controversial recount ensued, with both campaigns claiming irregularities.


2018 United States Senate election in Florida, General election, Initial results and recount
Both candidates traded accusations of voter suppression and voter fraud. Two lawsuits were filed by the Scott campaign after the election against the Supervisor of Elections in both Palm Beach and Broward Counties while the Nelson campaign filed one against the Secretary of State in Florida. On November 9, the Scott campaign won both of their lawsuits while the Secretary of State lawsuit has yet to be decided. Notably, election officials in Broward County had to receive police protection after accusations of voter fraud were made by a few members of Congress.


2018 United States Senate election in Florida, General election, Initial results and recount
Additionally, a number of mail-in ballots were found in a mail distribution center in the city of Opa-locka three days after the election. The Miami-Dade Elections Department considered the votes to be uncountable due to not making it to the department by the close of polls.


2018 United States Senate election in Florida, General election, Initial results and recount
The deadline for all ballots to be machine counted was 3pm EST on Thursday, November 15, 2018, and the revised totals triggered a statewide hand-recount of rejected ballots (also for Florida Agriculture Commissioner). At least three counties (Broward, Hillsborough, and Palm Beach County) missed the deadline.


2018 United States Senate election in Florida, General election, Initial results and recount
In addition, Lee County determined that they had not properly sorted out the number of undervotes on ballots for manual recount. The initial number was approximately 4,000 votes before the machine recount brought the number to around 15,000 votes. This delayed the counting process until the votes were properly separated.


2018 United States Senate election in Florida, General election, Results
Florida elections officials announced on November 18, 2018 that Scott had prevailed. Scott received 50.05% of the vote, while Nelson received 49.93%; the margin of victory was 10,033 votes out of 8.19 million votes cast. Nelson then conceded the race to Scott.


2018 United States Senate election in Hawaii

2018 United States Senate election in Indiana
The 2018 United States Senate election in Indiana took place on November 6, 2018, along with other elections to the United States Senate and House of Representatives and various state and local elections. Incumbent Democratic U.S. Senator Joe Donnelly sought reelection to a second term, facing Republican businessman and former state representative Mike Braun and Libertarian Party nominee Lucy Brenton. In 2017, Politico described the race as "possibly the GOP's best opportunity to seize a Senate seat from Democrats" in the 2018 elections. The primary election was held on May 8, 2018. In October 2018, RealClearPolitics rated the race a toss-up between the Democratic and Republican nominees, with the Libertarian receiving a poll average of 6%. Braun defeated Donnelly in the general election by a margin of 5.96 percent.


2018 United States Senate election in Indiana, Background
In 2012, Joe Donnelly was elected to the Senate with 50% of the vote to Republican nominee Richard Mourdock's 44%. In the 2016 presidential election, Republican nominee Donald Trump won Indiana with about 56.5% of the vote to Democratic nominee Hillary Clinton's 37.5%.


2018 United States Senate election in Indiana, General election, Results
On November 6, 2018, Braun won the general election. He swept southern Indiana, the exurbs of Indianapolis, and most other rural areas in the state. Donnelly ran well behind his 2012 vote totals, winning only in Indianapolis, the college towns (Bloomington, Terre Haute, West Lafayette, South Bend), and the suburbs of Chicago in Northwest Indiana.


2018 United States Senate election in Maine
The 2018 United States Senate election in Maine was held on November 6, 2018, alongside a gubernatorial election, U.S. House elections, and other state and local elections. Incumbent Independent Senator Angus King won reelection to a second term.


2018 United States Senate election in Maine
The U.S. Senate elections were conducted with ranked-choice voting, as opposed to a simple plurality, after Maine voters passed a citizen referendum approving the change in 2016 and a June 2018 referendum sustaining the change. Ranked choice voting was used in the primary elections as well. The first round of each election saw a majority and the instant runoff did not need to be carried out.


2018 United States Senate election in Maine, Background
A part of New England, Maine was once a bastion of the Republican Party, and was one of two states to vote against Franklin Roosevelt all four times he ran for president. Lyndon Johnson won the state in 1964, and Hubert Humphrey carried it in 1968 before the state reverted to form and reestablished a GOP voting streak that lasted until the 1990s. With the GOP progressively becoming more culturally conservative, the state began moving toward the Democrats, and Bill Clinton carried it in 1992. Clinton's win established a Democratic winning streak that lasted until Donald Trump won an electoral vote from the state's second congressional district in 2016 despite losing the rest of the state.


2018 United States Senate election in Maine, Background
The state has a tradition of electing various independent candidates to high office, such as Angus King, who served as governor of the state from 1995 to 2003. In 2012, King's decision to run for the Senate seat being vacated by Republican Olympia Snowe dramatized the battle for the Senate, as he left open whether he would caucus with the Republicans or the Democrats. He eventually decided to caucus with the Democrats and has established a center-left voting record.


2018 United States Senate election in Maine, Independents
King said his reelection plans would not be affected by treatment for prostate cancer, which he announced he had on June 22, 2015.


2018 United States Senate election in Maine, Republican primary
On January 12, 2015, Maine Governor Paul LePage made a statement on Howie Carr's radio program that he might run for U.S. Senate against King, citing King's switching his endorsement in the 2014 gubernatorial election from independent candidate Eliot Cutler to Democratic candidate Mike Michaud as a "horrible thing to do". The next day, LePage said his comment was a joke, though on an August 25, 2015 appearance on Carr's program, he said he was "very strongly" considering running, citing King's caucusing with Senate Democrats.


2018 United States Senate election in Maine, Republican primary
LePage also criticized King for his involvement in the Maine wind energy industry, saying King "ripped us off by $104 million during his eight years as governor – he ripped us off, royally, and I can’t wait until 2018 because I’m thinking that’s the guy I'm going after." A spokesman for King dismissed LePage's criticism.


2018 United States Senate election in Maine, Republican primary
On May 10, 2016, LePage announced at a town hall meeting in Oakland that he would run against King unless he was hired by the Donald Trump administration. On May 10, 2017, LePage decided not to run; his spokesman said he preferred to focus on being governor. On July 20, 2017, LePage again said he "might" challenge King. Trump personally encouraged LePage to run and offered his endorsement. LePage did not file to run by the March 15, 2018 deadline.


2018 United States Senate election in Maine, Republican primary
Eric Brakey's campaign successfully contested 258 signatures to Max Linn's petitions to appear on the primary ballot, which meant that Linn had 10 fewer signatures than the 2,000 needed to be on the ballot. Maine Secretary of State Matthew Dunlap then declared Linn ineligible to be a candidate, although it was too late to remove Linn's name from the ballot. Voters were informed of Linn's status when they voted, and any votes cast for him were counted as blanks. Nevertheless, Linn's campaign was active on Twitter and placed campaign signs along roads in Maine.


2018 United States Senate election in Maine, Republican primary
Linn signs were also seen in New Hampshire, including in Dover. Dover city officials said they would remove the signs upon request if Linn's campaign did not remove them, because Linn is not a candidate in a New Hampshire election and because the signs were placed improperly. Linn appealed the decision to disqualify him to U.S. District Court in Portland, but Judge Nancy Torresen rejected Linn's request for an injunction to bar Dunlap from informing voters he is ineligible. Linn subsequently announced he would run against U.S. Senator Susan Collins in the 2020 Republican primary election.


2018 United States Senate election in Maine, Democratic primary
The Democratic primary race initially included both teacher Zak Ringelstein and homebuilder Benjamin Pollard, but Pollard withdrew to run as an Independent two days after Ringelstein announced a list of 16 endorsements from Democratic state legislators. Ringelstein was the only major-party candidate for Senate to be a dues-paying member of the Democratic Socialists of America in 2018.

2018 United States Senate election in Michigan

2018 United States Senate election in Michigan, Republican primary, Debates
A debate was held between John James and Sandy Pensler on July 6 and televised by WKAR-TV. It was the only televised debate scheduled between the two candidates.


2018 United States Senate election in Michigan, Green Party Convention
The Green Party of Michigan picked their candidates at a state convention on May 5, 2018.


2018 United States Senate election in Michigan, General election, Results
Although Stabenow ended up winning the election by 6.5 percent, the margin was smaller than expected, considering the polling and past results of Senate elections in Michigan. Part of the relative closeness of the race has been attributed to the Stabenow campaign having run no negative ads against James during the election. Although James won most of Michigan's smaller counties, Stabenow won large margins in urban areas and modest margins in suburban areas. Stabenow trounced James in Wayne County, home of Detroit, and also performed well in Detroit's suburbs.


2018 United States Senate election in Michigan, General election, Results
She also easily won in Washtenaw County, home of Ann Arbor and Ingham County, home of Lansing. Kent County, home of Grand Rapids, also narrowly flipped to Stabenow, making this the first Senate election of her career in which she carried the county, and also the only county to flip her direction in 2018, and only the second time (after Carl Levin in 2008) a Democrat had carried the county since Donald Riegle in 1982. In addition to Stabenow's win, Democrats won the previously Republican-held offices of Governor, Secretary of State, and Attorney General, ensuring that as of January 1, 2019, all elected statewide officials would be Democrats.


2018 United States Senate election in Minnesota

2018 United States Senate election in Missouri
Incumbent senator Claire McCaskill ran for re-election in a primary field of eight Democrats. Eleven Republicans vied for their party's nomination which went to State Attorney General Josh Hawley, who filed notification in August 2017 that he had formed an exploratory campaign committee for the seat.


2018 United States Senate election in Missouri
The candidate filing deadline was March 27, 2018, and the primary election was held on August 7, 2018. Pollsters predicted a tight race. On November 6, 2018, Hawley was elected with 51.5% of the vote, to McCaskill's 45.4%, resulting in Republicans holding both Senate seats in Missouri for the first time since McCaskill took office in 2007. Hawley was also the youngest incumbent senator at that time and was until the election of Jon Ossoff in 2021.


2018 United States Senate election in Missouri, General election, Results
Sen. McCaskill conceded a few hours after the polls closed on Election day. Despite performing strongly in the St. Louis suburbs, she ran well behind her 2012 vote in Southeast Missouri, especially in the Lead Belt and the Missouri Bootheel. She also ran poorly in the northern part of the state. Despite McCaskill's loss, Missouri Democrats held the other statewide office that went up for election in this cycle, the office of Missouri State Auditor. Democratic incumbent state auditor Nicole Galloway, who had been appointed to the post in 2015 by then-Gov. Jay Nixon following a vacancy, won a full term in the 2018 State Auditor election.

The 2018 United States Senate election in Montana was held on November 6, 2018, to elect a member of the United States Senate to represent the State of Montana, concurrently with other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections.


2018 United States Senate election in Montana
Although Montana went for Donald Trump by a margin of about 20 percent in 2016, incumbent Democratic Senator Jon Tester was reelected to a third term, defeating Republican State Auditor Matt Rosendale. Rosendale conceded on November 7, 2018. This was the first Senate election in which Tester received a majority of votes cast rather than a simple plurality.


2018 United States Senate election in Montana, Libertarian primary, Candidates, Nominated
In October 2018, Breckenridge told a reporter from the Associated Press that he opposed the use of dark money in politics. Breckenridge said that he realistically anticipated only receiving three or four percent of the vote in the general election, and that he endorsed Rosendale's efforts to stop the use of dark money in politics. The Associated Press interpreted Breckenridge's comments as a statement that Breckenridge was dropping out of the race and endorsing Rosendale. Breckenridge later stated that his use of the word "endorse" referred only to stopping the use of dark money in politics, and said he was still running for the Senate.

2018 United States Senate election in Nevada
The 2018 United States Senate election in Nevada took place November 6, 2018, to elect one of two U.S. senators from Nevada. Democratic nominee Jacky Rosen defeated Republican incumbent Dean Heller.


2018 United States Senate election in Nevada
Heller had considered a bid for Nevada governor but instead announced he would run for reelection to a second full term. He was the only incumbent Republican senator running in a state that Hillary Clinton won in 2016. Rosen's victory marked the first time that Nevada has been represented by two women in the United States Senate, and the first time a Democrat had won the Class 1 Senate seat in Nevada since 1994 (as well as the first time both Senate seats were held by Democrats since 2001). Heller was the only Republican incumbent to lose a Senate seat in 2018.


2018 United States Senate election in Nevada
The candidate filing deadline was March 16, 2018, and the primary election was held on June 12, 2018.


2018 United States Senate election in Nevada, Background
Nevada is a swing state that once leaned slightly rightward, having voted for George W. Bush twice. But since 2008 it has seen the opposite trend, giving Barack Obama a seven-point victory in 2012 while simultaneously electing Heller to the Senate by one point. Obama also carried Nevada in 2008 by a 12.5% margin. In 2016, the state shifted rightward again, still voting for Hillary Clinton, but only by two points, although Democrat Catherine Cortez Masto managed to win the seat of retiring Democratic Senate leader Harry Reid.


2018 United States Senate election in Nevada, Background
Because of the consistent swing nature of the state, many cited Heller as the most vulnerable incumbent Republican in the U.S. Senate up for reelection in 2018, a year with few Republicans in that position; President Donald Trump even warned that if Heller failed to vote to pass the GOP Health care bill to repeal and replace the Affordable Care Act, he could well lose his seat in the next election.


2018 United States Senate election in Nevada, Background
At the end of September 2018, the Brett Kavanaugh Supreme Court nomination became a major element of the campaign. Heller made noncommittal remarks and a significant campaign was deployed to criticize his support for Kavanaugh.


2018 United States Senate election in Nevada, Background
Rosen is only the 37th sitting House freshman to win a Senate election, and the first female Representative to do so.


2018 United States Senate election in Nevada, General election, Results
Heller carried 15 of Nevada's 17 county-level jurisdictions, but Rosen carried the two largest, Clark (home to Las Vegas) and Washoe (home to Reno). She won Clark County by over 92,000 votes, almost double her statewide margin of over 48,900 votes.


2018 United States Senate election in New Jersey
The 2018 United States Senate election in New Jersey  took place on November 6, 2018, in order to elect a member of the United States Senate to represent the state of New Jersey. Incumbent Democratic U.S. Senator Bob Menendez won reelection to a third term over Republican businessman Bob Hugin.


2018 United States Senate election in New Jersey
The candidate filing deadline was April 2, 2018, for Democratic and Republican candidates, and the primary election was held on June 5, 2018. The deadline for independent candidates was June 5, 2018.


2018 United States Senate election in New Jersey
Despite the race being rated as a tossup by some political pundits, including The Cook Political Report, Menendez was reelected by an 11.2% margin. However, Hugin was the first Republican Senate candidate to carry Atlantic and Gloucester counties since Clifford Case's landslide victory in 1972.


2018 United States Senate election in New Jersey, Democratic primary
While he never lost support from any major New Jersey officials, after a mistrial was declared in Senator Menendez's corruption trial, party figures across New Jersey lined up with public endorsements of his reelection bid, including the "full support" of Governor Phil Murphy. He formally declared his intention to run for reelection on March 28, 2018, alongside Governor Murphy and Senator Cory Booker.


2018 United States Senate election in New Jersey, Republican primary
Bob Hugin launched his primary campaign on February 13 in Springfield. He began advertising on television two weeks later, attacking Menendez on the airwaves, and was soon considered the presumptive nominee. His opponent, Brian Goldberg, attempted to connect himself to President Donald Trump and his supporters by inserting the President's abbreviated slogan, "MAGA", into his ballot slogans and aligning himself with other pro-Trump, anti-establishment candidates. Goldberg also attacked Hugin's running mates, urging Republicans to write in the deceased Charlton Heston in primary races where a Republican congressional candidate was running unopposed. Ultimately, Hugin won overwhelmingly with a majority of votes in each of the state's 21 counties.


2018 United States Senate election in New Mexico
The 2018 United States Senate election in New Mexico took place on November 6, 2018, to elect a member of the United States Senate to represent the state of New Mexico, concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections.

2018 United States Senate election in New Mexico
The candidate filing deadline was March 13, 2018. The Republican and Democratic primary elections were held June 5, 2018. Johnson's results were the highest results for a Libertarian candidate in New Mexico history.


2018 United States Senate election in New Mexico, Libertarian primary
On July 30, 2018, nominee Aubrey Dunn withdrew from the race. On August 4, former governor Gary Johnson was formally nominated by the Libertarian Party of New Mexico as Dunn's replacement. Johnson accepted his party's nomination on August 13.

2018 United States Senate election in North Dakota
The 2018 United States Senate election in North Dakota took place on November 6, 2018, to elect a member of the United States Senate to represent the State of North Dakota, concurrently with other elections to the U.S. Senate, as well as other federal, state and local elections in North Dakota.


2018 United States Senate election in North Dakota
Incumbent Democratic-NPL Senator Heidi Heitkamp ran for reelection to a second term. The candidate filing deadline was April 9, 2018, and the primary election was held on June 12, 2018. U.S. Representative Kevin Cramer won the Republican primary to challenge Heitkamp, who ran unopposed in the Democratic primary.


2018 United States Senate election in North Dakota
On November 6, 2018, Cramer defeated Heitkamp in the general election, becoming the first Republican to win this seat since 1960.


2018 United States Senate election in North Dakota, Background
Many observers cited Heitkamp as a vulnerable incumbent Democrat in 2018, as she balanced cooperation with her Democratic colleagues in the U.S. Senate with pleasing her constituents in deeply Republican North Dakota; Donald Trump won in North Dakota by about 36 points. The race was expected to be extremely competitive and some projected it would be the most expensive race in North Dakota history.


2018 United States Senate election in North Dakota, Background, Voter ID law and Native Americans disenfranchisement
On October 9, 2018, the Supreme Court of the United States upheld North Dakota's voter ID law, called HB 1369. This law requires voters to use an ID which lists a street address, and doesn't allow PO boxes as valid addresses. However, many Native American reservations don't use a conventional address system and their inhabitants tend to use PO boxes instead, making a large share of the IDs used by Native Americans invalid. Although both Natives and non-Natives are affected, Native Americans are disproportionately more likely to be affected by HB 1369, and the law has been criticized for disenfranchising Native Americans.


2018 United States Senate election in North Dakota, Background, Voter ID law and Native Americans disenfranchisement
The Republican-held state government of North Dakota argued that the law was created to prevent voter fraud, but has been accused of passing the law because Native Americans are likely to vote Democratic. HB 1369 had previously been found to be invalid by the Court of Appeals for the Eighth Circuit, for which reason it didn't affect the primary elections earlier in 2018, but the Supreme Court decision meant that many people didn't have the right ID and were ineligible to vote in the general election.


2018 United States Senate election in North Dakota, Democratic-NPL primary
The Democratic-NPL Party held their state convention March 16 and 17, during which delegates voted to endorse  Heitkamp for re-election. Although general election ballot access is actually controlled by a primary election, challenger Dustin Peyer did not challenge Heitkamp in the June 2018 primary.


2018 United States Senate election in Ohio
The 2018 United States Senate election in Ohio took place November 6, 2018. The candidate filing deadline was February 7, 2018; the primary election was held May 8, 2018. Democratic U.S. Senator Sherrod Brown—the only remaining elected Democratic statewide officeholder in Ohio at the time of the election—won his reelection bid for a third term, defeating Republican U.S. Representative Jim Renacci in the general election.


2018 United States Senate election in Ohio, General election, Results
The election was not particularly close, with Brown winning by 6.84%. Brown was the only Democrat who won statewide in Ohio in this election cycle. Brown was able to win re-election by winning back most of the Rust Belt, which swung Republican in 2016. Brown did well in Portage County, Summit County, and Trumbull County, which are all very heavily pro union counties. Brown also did well in the rust belt from Lucas County, home of Toledo, all the way to Cuyahoga County, home of Cleveland.


2018 United States Senate election in Ohio, General election, Results
Brown also trounced Renacci in Franklin County and Hamilton County home of Columbus and Cincinnati respectively; the latter, Hamilton County was once considered a Republican stronghold. Renacci, while performing well in most rural areas of the state, underperformed Mike DeWine, the Republican Party's nominee and eventual winner for governor. Regardless, Renacci somewhat overperformed in comparison to most polling before the election, while Brown lost in several counties he had won in his previous Senate races. Exit polls also show Brown had a very strong showing amongst minority and women voters, which was key to his victory. Brown was sworn in for a third term as the senior senator from Ohio on January 3, 2019.


2018 United States Senate election in Ohio, General election, By congressional district
Brown won 9 of 16 congressional districts, including the 1st, 10th, 12th, 14th and 15th  districts, which elected Republicans to the House.
