Jim DeMint thinks 2012 GOP front-runner "will change several times"

Robert Costa of National Review quotes U.S. Senator Jim DeMint (R-SC), who helped organize today's Palmetto Freedom Forum:

"Some that don’t appear to be in the running right now were pretty good on stage today," he said. "I don't think this race is over. I think we’re going to see that front horse change several times, I think, over the last couple months."

Costa titled his post: "Newt? Cain? Paul?"
