Republican candidates face off in Iowa

Nearly two months after their last debate, the Republican presidential candidates gathered on stage at Iowa State University in Ames last night, for another national televised debate. Rep. Michele Bachmann and former Governor Tim Pawlenty, both from Minnesota, sparred about their records. Who dominated? And who stumbled? We’re speaking with Terry Holt,  a Republican political strategist. Holt served as the national spokesman for the Bush-Cheney campaigns in 2000 and 2004. He talks about how the candidates tried to distinguish themselves in a crowded field.
