Mary may be back in 2016 on the HRC ticket running for the Vitter seat.
I don’t think so. Her “brand” is irreparably damaged. In fact, her defeat cratered her brother’s chances for Louisiana governor, according to some pundits.

2. Mitch Landrieu — The mayor may not want to admit it, but his sister’s defeat in the Senate race means he can forget about running for governor next year. If he does run, the only thing he’ll accomplish is guaranteeing the election of David Vitter. Like his sister, Mitch Landrieu will be easily tied to Barack Obama if he tries to run statewide next year. (The President endorsed the mayor’s re-election in January and will still be president — and unpopular — next autumn.) That should make it easy for the mayor to keep his campaign promise to serve out his second term.
On whose dime? She's as broke as she is fat. The Dems are gonna pull out their ad buy money in '14 just to give it back to her in '16? I don't think so. She'll be forever remembered for her Obama-fawning ways and thus forever toxic.
