With Rick Scott continuing to struggle in the polls, chatter keeps on coming that the governor could face a challenge for the Republican nomination in 2014. But if it's going to come, it likely won't be from Washington.

An old foe resurfaced last week to insist Scott could face a primary in 2014. Former Attorney General Bill McCollum closed the door on challenging Scott in the Republican primaries next year. During the 2010 election cycle, the governor defeated McCollum in a close and bitter contest.

Unlike several vice presidential candidates in recent years, U.S. Rep. Paul Ryan of Wisconsin can count on the support of his running mate if he sets his sights on the Republican presidential nomination -- and recent signs indicate that Ryan is going all out to raise his profile.

In an interview with CBS News Thursday morning, Ann Romney, wife of defeated Republican presidential candidate Mitt Romney, said she and her husband are behind Ryan if he runs for president in 2016.
