Rick Santorum won his first state since Iowa by a resounding 30-point margin. In the Missouri primary, Santorum took 55.2% of the vote to Mitt Romney's 25.3% and Ron Paul's 12.2%, according to the AP. Newt Gingrich wasn't on the ballot, an omission his campaign said was deliberate. The primary is a non-binding "beauty contest," with Missouri awarding its delegates after caucuses next month. "Conservatism is alive and well in Missouri and Minnesota!" he told cheering supporters at a rally in Missouri. (More Missouri primary stories.)
