Politics Day: Obama in Iowa
President Obama makes another stop in our fair swing state of Iowa. Mitt Romney pivots toward the general election... campaigning with Florida Senator Marco Rubio, as the Veepstakes heat up. And the trial of John Edwards on federal campaign finance charges in North Carolina. Host Ben Kieffer talks with analysts Tim Hagle of the University of Iowa and Dennis Goldford of Drake University about these and other issues in our weekly political discussion.
