Santorum already eyeing next stop: Florida

COLUMBIA, S.C. — With the race in South Carolina here seemingly between Mitt Romney and Newt Gingrich, Republican hopeful Rick Santorum is bracing for a setback and looking ahead to the next contest. That's the Florida primary.

Santorum plans to visit polling locations and attend an evening rally in Charleston on Saturday before his campaign moves south.

Santorum's advisers say he will have no reason to exit the four-man race for the GOP nomination after voting ends. His allies say he's going into primary day a winner in Iowa's lead-off caucuses and with a better showing than Gingrich in New Hampshire.

During campaign stops leading up to Saturday's poll openings, Santorum had cast himself as a Goldilocks candidate: just right when compared to Gingrich's "too hot" rhetoric and Romney's "too cold" personality.
