During last night’s Huffington Post Game Changers event at Skylight Soho, Beau Biden scoffed at the possibility that his father, Vice-President Joe Biden, would swap positions with Secretary of State Hillary Clinton for President Obama’s reelection run. “I marvel,” Biden, Delaware’s attorney general, told us. “You guys are too busy to play the parlor game. You’ve got more important things on your hands.” Granted, the long-rumored switcheroo may not exactly be the most pressing news story of the day … but is there any truth to it? “No. It’s not happening,” Biden insisted. “I’ll bet you dinner.” Nah. We don’t think it’s happening either.
