South Carolina ? Rudy Giuliani on whether he’ll run for president: “There’s a real good chance.”

The former New York City mayor has been keeping an itinerary bringing him to all the campaign trail hot spots but told The Associated Press on Saturday he hasn’t decided yet whether he could make a “unique contribution” to the nation.

Giuliani formed a presidential exploratory committee in November to prepare for a possible bid for the GOP nomination in 2008. It lets him raise money and travel the country, gauging how much support there could be for him. In his few first weeks, Giuliani took in $1.4 million.

The Republicans’ top tier of candidates for 2008 includes Arizona Sen. John McCain, former Massachusetts Gov. Mitt Romney, former Arkansas Gov. Mike Huckabee and Kansas Sen. Sam Brownback.
