Biden's Debate Soundtrack

JOHNSTON, Iowa - Outside the site of today's Des Moines Register Democratic presidential debate, enthusiastic groups of supporters greeted arriving audience members waving signs, cheering, singing and - getting crunk?

Delaware Senator Joe Biden's supporters danced to the hip-hop hit "This Is Why I'm Hot" by Mims as it blared from two large speakers set up behind them. But not long after the rapper delivered the seemingly less Biden-friendly line "I represent New York," the tune quickly changed - to the Beach Boys classic "Good Vibrations."
