Perry out; Santorum won Iowa

Rick Perry dropped out of the GOP presidential race today and endorsed challenger Newt Gingrich. “I have come to the conclusion that there is no viable path forward for me in this 2012 campaign,” said Perry (in photo), who was an instant front-runner when he entered the campaign but then faded nearly as quickly. Meanwhile, it appears that Rick Santorum won the Iowa caucuses after all. He leads Mitt Romney by 34 votes, though results from eight precincts aren’t yet included.
