Republican presidential hopeful Mitt Romney
Mitt Romney may have won the Iowa caucuses last night, but he won by a mere 8 votes. Rick Santorum's rise propelled him to a close second and Ron Paul came in third. Michele Bachmann, who came in sixth, announced today that her bid for the presidency is over. Here to talk about the latest in the GOP primary race is Christina Bellantoni, political editor for PBS' Newshour.
