So does his proclamation extend to running for re-election to his Senate seat in 2016, should he fail in his drive for the mansion?
One line from U.S. Sen. David Vitter's announcement for governor in January stood out more than others: "This will be my last political job, elected or appointed, period."
It jumped off the page and screen because some viewed it as a thinly-veiled swipe at Gov. Bobby Jindal, who has gradually inserted himself on the national political stage and is undoubtedly running for president.
Vitter has been using the pledge on the campaign trail, most recently in Thibodaux.

"I'm not really focused on that right now," Vitter told LaPolitics when asked whether the 2015 contest will be his last. "I'm only focused on this race for governor."
If he is elected, one of his first official acts would be to appoint his Senate replacement, which has spurred speculation of how that would factor in his campaign. It won't, pledged Vitter.
"There will be absolutely no understanding, arrangement or deal tying any appointment to the campaign in any way," he said.
