Rick Perry to Drop Out of GOP Race

And then there were four: Rick Perry will drop out of the GOP race this morning, sources tell Politico. He will make the announcement at an 11am press conference, in which he is expected to endorse Newt Gingrich. The move fulfills 50% of Gingrich's hope that both Ricks drop out, and Politico notes that Perry's exit will likely give the surging Gingrich a boost in tonight's debate and Saturday's primary.
