 "I believe that as our next Governor, I can have a bigger impact addressing the unique challenges and opportunities we face in Louisiana," the senator said in an email first obtained by The Associated Press from a member of Vitter's staff. 
  
 Vitter's announcement ends months of speculation about his intentions, and his decision is expected to influence which other potential candidates enter the race. 
  
 Gov. Bobby Jindal is term-limited, so the race is wide open. Vitter can run without forfeiting his Senate seat, which isn't up for re-election until 2016. 
  
 Vitter said that as governor, he would push for excellence in education, budget stability, tax and spending reform, and government accountability. 
  
 "This will be my last political job, elected or appointed, period. So my only agenda will be to do what's best for all Louisianians, from our best and brightest to our most vulnerable," he said in the email. 
  
 Others who have said they will run for governor include: Republican Lt. Gov. Jay Dardenne and state Rep. John Bel Edwards, chairman of the House Democratic Caucus. State GOP Treasurer John Kennedy has said he is considering entering the race. 
  
 Vitter has proved to be a resilient politician, holding elected office for more than two decades as a state and federal lawmaker and easily winning re-election to a second U.S. Senate term in 2010, despite ties to a prostitution scandal. 
  
 Vitter admitted to a "serious sin" after phone records linked him to Washington's "D.C. Madam" prostitution case in 2007. He hasn't commented further on whether he broke the law, instead saying his family had forgiven him and moved past it. ||||| Vitter says his 'active campaign' won’t start until next year. Vitter to run for governor in 2015 
  
 Sen. David Vitter announced on Tuesday morning that he will run for governor of Louisiana in 2015. 
  
 “I believe that as our next governor I can have a bigger impact addressing the unique challenges and opportunities that we face in Louisiana,” Vitter said in a Youtube video launching his gubernatorial run. Along with the 2.5-minute video, Vitter also unveiled a new website touting his credentials and soliciting contributions to his campaign.

 The conservative Republican said that for now, he will continue to focus on his work in the Senate. While his “active campaign” won’t start until next year, the senator has already begun laying the groundwork for it by holding hundreds of listening sessions across Louisiana. He said this will be his “last political job, elected or appointed. Period.”

 As governor, Vitter said he would work to improve Louisiana’s lagging education system, make the state more business-friendly and also work to clean up the state’s politics. 
  
 “Through it all we’ll do it by fighting political corruption and demanding government reform and accountability. That’s a battle I’ve long waged,” Vitter said, a reference to his single-minded pursuit of curtailing the implementation of Obamacare. 
  
 If Vitter wins, he’d have the ability to appoint his own replacement to the Senate. Some Louisiana insiders say he could appoint a placeholder who wouldn’t run for reelection in 2016. 
  
 Others say he would use the potential of a Senate appointment down the line to keep potential GOP opponents out of the governor’s race now. State Treasurer John Kennedy, for example, has said he’s interested in running for governor. But as a past Senate candidate he could be swayed by the possibility of a seat in the upper chamber down the line.

 “Vitter’s going to be looking to clear the field, or at least limit the field, and one way to do that is to cut a deal,” said Bob Mann, a former press secretary to Gov. Kathleen Blanco and Sen. John Breaux. “Such an arrangement, spoken or unspoken, could benefit both people.” 
  
 And if Vitter loses in 2015, he could potentially run for reelection as a senator a year later when his term is up. 
  
 As for the 2016 race that would be triggered by a Vitter gubernatorial win, Louisiana political types say it would likely draw a wide range of GOP House members and statewide elected officials, plus potentially some state legislators as well. 
  
 Longtime Louisiana pollster Bernie Pinsonat said he expects the number of potential GOP candidates to be in double digits, with “at least three or four or five” eventually running. 
  
 Some of those candidates could include Lt. Gov. Jay Dardenne, former Rep. Jeff Landry and current Reps. Steve Scalise, John Fleming and Vance McAllister. If Rep. Bill Cassidy and state Rep. Paul Hollis, who are both running in this year’s Senate race against Democratic incumbent Mary Landrieu, ended up losing, they could also be contenders for Vitter’s seat in 2016. 
  
 On the Democratic side the field is less clear — and, assuming Vitter appoints a GOP successor to the seat, any Democratic candidate would be starting at a disadvantage against someone with the benefits of incumbency. 
  
 Some said that Landrieu, who’s up for reelection this year, could run for Vitter’s seat in 2016 if she loses this November. There’s also New Orleans Mayor Mitch Landrieu, Mary Landrieu’s brother, who has strong name ID throughout the state and may be a contender in 2016 if the seat opens up. 
  
 And one other potential Democratic candidate could be John Bel Edwards, who’s currently running for governor. If he lost to Vitter in 2015, he might consider running for Senate the following year. 
  
 Vitter has spent much of the past six months positioning himself as a Washington outsider, sometimes infuriating his colleagues in the process. Vitter is fixated on eliminating a federal health care contribution to Capitol Hill staffers and administration officials, dubbing it an “exemption” for Washington. 
  
 This quest privately rankled Republican staffers on the Hill, mostly because the so-called “Vitter amendment” would raise their health-care costs and essentially lower their salaries. His insistence on getting a vote on that legislation was blamed for single-handily derailing a noncontroversial, bipartisan energy efficiency bill. 
  
 Vitter is betting that his record of cooperation on popular infrastructure bills paired with his dogged pursuit of the “Vitter amendment” and pointed critiques of the Environmental Protection Agency have set him up to pursue the governor’s mansion as a reliable conservative lawmaker who can also get things done for Louisiana. 
  
 Vitter also backed Senate conservatives’ strategy of opposing any government funding bill that included money for Obamacare, defying Senate GOP leadership and contributing to a lengthy government shutdown in October. And the GOP senator still has political baggage from his connection to a prostitution scandal in 2007. Though he overcame that narrative to easily win reelection in 2010, it’s certainly not forgotten by national Democrats, who threatened to dredge it up on the Senate floor. 
  
 But Vitter has also sought to distinguish himself as a bipartisan deal-maker, particularly in his new role as the ranking Republican on the Senate Environment and Public Works Committee. He helped blunt conservative attacks on the Senate-passed water bill — largely believed to be generous toward Louisiana — and will play a leading role alongside Chairwoman Barbara Boxer (D-Calif.) in seeking to pass a highway bill later this year. ||||| Sen. David Vitter (R-La.) will run for governor in 2015. The early read is that he stands a pretty decent (if not better) chance of winning.

 That's pretty remarkable. In 2007, Vitter was an embattled senator apologizing in public after his number appeared in the telephone records of the "D.C. Madam." 
  
 So how did he survive the cloud of a prostitution scandal where other have failed? A combination of luck and skill. 
  
 On the luck side, timing had a lot to do with it. The Post's Paul Kane took a deeper dive into Vitter's career arc last year. As Kane reported, the fact that 1) Vitter didn't have to go before voters until years after the "D.C. Madam" revelation and 2) The year he did was a banner one for Republicans fueled by deep unhappiness with President Obama helped him a keep a job that may well have slipped away under less favorable circumstances. 
  
 Vitter did his part to keep a low profile as he worked his way back and cooperated with Democrats once he was. Plus, it certainly didn't hurt that charges never materialized. From Kane's story: 
  
 Vitter also kept his head down. He worked to rehabilitate his image back home in one of the smartest or luckiest (perhaps both) twists of political fate in recent years. He was never criminally charged. The Senate Ethics Committee, chaired by Boxer, dismissed the case, finding that whatever the conduct was, it occurred “before your Senate candidacy” in 2004 and “did not involve use of public office.” Few Democrats will openly forgive Vitter’s alleged actions — he never spelled out what precisely occurred with the madam’s clients — but they say they have found in the reengaged senator someone who is willing to work across the aisle on some issues. 
  
 Vitter has long been rumored as a candidate for governor. So his announcement Tuesday that he will run is not a surprise. It comes as he has not only strong name recognition from his years as a statewide officeholder; he's popular, too. 
  
 One recent poll showed Vitter with high approval ratings and a lead on the potential 2015 field, topping two other statewide officials, Lt. Gov. Jay Dardenne (R) and Treasurer John Kennedy (R). Another one also showed him at the top of the heap. 
  
 There's no one recipe for dealing with scandal. Every case is unique. But what Vitter's survival shows is that time is often a scandal-plagued pol's best friend. And what an incumbent does with the time before voters get to pass judgement on them at the ballot box can prove to be critical. 
  
 It's possible the "D.C. Madam" story could surface again in Vitter's campaign for governor. Opponents might be tempted to raise the issue in a heated race. But such kinds of attacks probably won't have anywhere near the potency they would have had in the immediate wake of the scandal. 
  
 Vitter said in his announcement that governor would be his last political office. Under different circumstances, his career in politics might have ended years ago. ||||| David Vitter Announces Run for Governor 
  
 By Kyle Trygstad and Meredith Shiner 
  
 Sen. David Vitter, R-La., announced Tuesday that he will run for governor next year, confirming the biggest open secret in Bayou State politics and on Capitol Hill. 
  
 “After much thought, prayer and discussion with Wendy and our children, I’ve decided to run for governor of Louisiana in 2015,” the second-term Republican says in a video on his redesigned campaign website. 
  
 Louisiana’s next gubernatorial election is in November 2015 — a year before Vitter’s Senate term would end. Should he lose, Vitter could keep his seat and decide whether to seek re-election. 
  
 If Vitter wins, he would have the power to appoint a successor to serve the final year of his term. 
  
 His announcement comes as Sen. Mary L. Landrieu, D-La., faces a challenging re-election campaign in 2014 against Rep. Bill Cassidy and other Republicans. Vitter’s gubernatorial bid means that ambitious members of his party may have another shot at the Senate just two years later. 
  
 On Capitol Hill, Vitter’s decision comes as no shock. For months, frustrated Senate Republican aides believed Vitter was pushing his health care amendment, which would have taken away employer contributions to plans of members and staff, as part of his pending gubernatorial campaign. 
  
 The so-called Vitter amendment provided him with an opportunity to prove his conservative bona fides in preparation for his gubernatorial run. 
  
 Otherwise, Vitter has largely stayed out of the spotlight since his prostitution scandal in 2007. He won re-election in 2010 with 57 percent of the vote. 
  
 Vitter first came to Congress in a 1999 special election to Louisiana’s 1st district following the resignation of Speaker-designate Bob Livingston, who had admitted to extramarital affairs. In 2004, Vitter won the seat of retiring Democratic Sen. John Breaux. |||||
A:
Conservative Sen. David Vitter announced today what pretty much everyone in Louisiana already knew: He's running for governor in next year's election, reports Roll Call. Bobby Jindal can't run again because of term limits, and Vitter "stands a pretty decent (if not better) chance of winning," writes Sean Sullivan at the Washington Post. That's not bad for a guy who had to publicly apologize after his name turned up in the little black book of the "DC Madam" in 2007, notes Sullivan. Vitter has kept a relatively low profile since the scandal, though he raised it in recent months to push the so-called "Vitter amendment," which would eliminate federal subsidies for Capitol Hill staffers, reports Politico. Most observers felt it was a deliberate move to burnish his conservative credentials ahead of a gubernatorial run, notes Roll Call. Vitter does not have to resign as senator to run, reports the AP. If he wins, he can appoint someone to serve out the final year of his term.
