Nearly three months after the Iowa Caucuses, the GOP race is still anyone's game. Rick Santorum won the Kansas Caucuses on Saturday, while Romney picked up delegates in Wyoming, as well as Guam, the Northern Mariana Islands, and the U.S. Virgin Islands. Newt Gingrich continues to trail Romney and Santorum, but he has campaigned aggressively in the South, where primary voters will go to the polls in Alabama and Mississippi on Tuesday. How will Mitt Romney fare in the South, a conservative stronghold? Do Santorum's wins in staunchly conservative states like Kansas and Oklahoma spell trouble for Romney? And how does Gingrich figure into the race going forward? Joining us is Jonathan Chait, a writer for New York Magazine.
