Corn on Hardball: Is the GOP Race Slipping Away?

David Corn and Time magazine’s Mark Halperin joined Chris Matthews on MSNBC’s Hardball to discuss the latest political poll results and what they say about the GOP’s chances in the 2012 election.

The polls also show that when Obama is pitted against Mitt Romney and Rick Santorum, he beats them by 10 and 11 points, respectively. The Republican primary fight has dragged on for months and promises to continue well into the future. Has all the candidates’ mudslinging started to harm the GOP’s image and turn off voters?
