Ron Paul is currently just behind Mitt Romney in the days leading up to the Iowa caucuses, but the congressman is already saying that he may not support any of his rivals for the nomination. In an interview with Bloomberg News, Paul says that he could not back them unless they adopted some of his priorities as their own. He added that the other candidates represent the “status quo.” However, Paul did say that Romney’s business experience would make him a better choice than Newt Gingrich. Meanwhile, Herman Cain is trying to grip tightly to his last bit of relevancy before he drifts off into the land of forgotten candidates by holding out on his endorsement until after the Iowa caucuses start Tuesday. In fact, Cain's campaign manager suggested to the AP that the former hopeful doesn't think any of the GOP candidates have proven themselves worthy of his endorsement.
