Last week on Politics Nation Radio, we talked with Philadelphia Mayor Michael Nutter, a big Hillary Clinton backer, and former DNC chairman David Wilhelm, Bill Clinton's old campaign manager and now a supporter of Barack Obama, about Obama's comments on Pennsylvanians clinging to bitterness, the debate over seating Florida and Michigan delegates at the convention and how Nutter was going to prepare for Monday's appearance on the Colbert Report.

In the second hour, Democratic Congressional Campaign Committee communications director Jennifer Crider and National Republican Congressional Committee press secretary Ken Spain go toe to toe on Louisiana special elections, Mississippi special elections and the House landscape as a whole. Later, we're joined by Hotline editor in chief Amy Walter and seersucker expert/barbeque wiseman/South Carolina Republican Party executive director Jay W. Ragley.
