Biden jokes on Letterman: ‘If you vote early, you don’t have to pay taxes’

Vice President Joe Biden hit "The Late Show with David Letterman" on Thursday, spreading the Obama campaign's gospel of early voting in a special "Top Ten List" five days before Election Day.

In an early preview provided by CBS, Biden uncorks a fine No. 6: "If you vote early, you don't have to pay taxes." The crowd roars with laughter as the vice president looked off-camera, then adds, "I'm sorry, I'm being told that's not accurate."

The vice president opens on a somber note, acknowledging the battering that New York and New Jersey took from deadly superstorm Sandy. "I just hope everything's coming along all right in New York," he says. "You've been devastated in New York and New Jersey, and just know that everyone's thinking of you and we're doing everything we can to help."

And then on with the show.No. 7: "In a less crowded polling center there's plenty of room to stretch out, linger and relax."

No. 5: "Single and looking to mingle? Find that special someone on the early voting line."

While the Obama campaign talks up the way some voters get the bulk of their information about politics from shows like Letterman's, the program has also been a serious venue. It was there, on Sept. 18, that the president first publicly blamed "extremists and terrorists" for the attack on the American compound in Benghazi, Libya.
