In Depth: New poll shows Gingrich leading GOP field

It's a scenario that seemed unimaginable just a few short months ago – Newt Gingrich has emerged as a front runner for the Republican presidential nomination.  According to a CNN/ORC International Poll released Monday, 24% of Republicans and Independents who lean towards the GOP say Mitt Romney is their likely choice for their party's presidential nominee with Gingrich at 22%. Romney's two-point advantage is well within the survey's sampling error.  The former Speaker of the House has risen fourteen points in the polls since October.

Today on American Morning, Carol Costello goes In Depth with Martin Frost, former Democratic congressman from Texas, and Rick Tyler, a former Gingrich spokesman, to discuss why GOP voters are now warming up to the former speaker.
