Cain Officially Endorses Romney

First he endorsed “the American people.” Then he threw his support behind Newt Gingrich. But now, as the GOP primary winds down, Herman Cain says he is backing Mitt Romney, the presumptive nominee. Cain admitted he has some major differences with Romney, but would campaign for the former Massachusetts governor moving forward. The one-time GOP frontrunner also said he would consider running for vice president if Romney asked him to join the ticket, but he denied rumors he would be running for governor in Georgia.
