Christie Endorses Romney

If you needed any further proof that Chris Christie isn't running, here it is: He endorsed Mitt Romney for president today, reports Fox News. "America cannot survive another four years of Barack Obama, and Mitt Romney is the man to lead America," the New Jersey governor said. His announcement came hours ahead of tonight's Republican presidential debate at Dartmouth College and a week after Christie said he wouldn't run himself. The debate, meanwhile, is being seen as do or die for Rick Perry. (More Chris Christie stories.)
