Santorum dismisses Romney's delegate math WASHINGTON, March 25 (UPI) -- Rick Santorum said crunching the numbers in the U.S. Republican presidential primary doesn't necessarily mean he is out of the race. Santorum, who won the Louisiana primary Saturday, said the polls and delegate counts still give him a shot at overtaking front-runner Mitt Romney, a former Massachusetts governor. "I don't agree with the delegate math that the Romney campaign is putting out there," Santorum said on CBS' "Face the Nation" Sunday. Santorum, a former U.S. senator from Pennsylvania, said Romney was padding his totals by laying claim to all of the delegates in certain states that are not necessarily winner-take-all states. "Before April 1 no state can be a winner take all," Santorum said, citing Republican National Committee's rulebook. So you're looking at probably 50 or more delegates that Gov. Romney has is going to be taken away from him. They're going to be proportioned between me and Congressman Gingrich. Santorum predicted his campaign will gain momentum, while Romney will become bogged down by his past actions on issues such as healthcare. Voters "are looking for someone who is going to win the election because they have better ideas not because they've been able to pound their opponent into the ground with overwhelming negative ads," Santorum said.
