Santorum downplays convention floor fight WASHINGTON, March 18 (UPI) -- Rick Santorum said he did not think hashing out the Republican presidential nomination at the convention would lessen the GOP's chances of winning in November. Santorum told ABC's "This Week" that the inability of Mitt Romney to put the nomination away early was a sign of a change within the party that was uniting conservatives such as himself. "It just tells you that people are looking for something different," Santorum said. They are looking for something that can go after President Obama and make the contrast. Santorum said the evolution worked in his favor because voters were seeing little difference between Obama and Romney, which would keep him in the primary race until the convention. Santorum also stated his case for elbowing Newt Gingrich out of the picture and declaring the race a two-man affair between himself and Romney. He repeated his challenge for a one-on-one debate with Romney, whom he accused of dodging him. "He's hiding behind the billionaires who are funding his super PAC and spending outrageous amounts of money," he said.
