Santorum: ‘It’s Halftme’

Rick Santorum may have suffered a triple defeat and be trailing in endorsements, money, and delegates—272 to Mitt Romney’s 646, according to the Associated Press—but he’s not bowing out yet. “It's halftime," he said at a rally in Mars, Pa., last night. He’s already begun campaigning in his home state of Pennsylvania, with three events scheduled there today, but he faces an uphill battle. The stakes for the April 24 primary are especially high for Santorum: not only would a loss there definitively scuttle his campaign, it would reverse much of the progress he’s made since his embarrassing 18-point loss in his 2006 Senate race.
