In the latest Celeb voting PSA, Gossip Girl hotties Penn Badgley and Blake Lively humorously compare the danger of voting McCain to the danger of doing drugs.

"If you're ever out somewhere and you're considering voting McCain, just call me," says Blake. "I'll pick you up. No questions asked."

It's 2008 and no longer is the message, "Talk to your kids about drugs. The new message is "Talk to your parents about McCain." They even set up a handy guide with tips on how to bring the discussion up with your parents, and how to win the argument.

“This will be the most important election of our lifetimes when you think about what is at stake. Young people get it, they are voting overwhelmingly for Barack Obama,” said director Doug Liman. “Too many of their parents are still on the fence and I thought it was important to make this ad and let my generation and older generations know that the younger generation is clear: they want a future and a country led by Barack Obama.”

Obama's got Gossip Girls behind him. If Blake or Chuck have anything to do with it, this election might be a done deal.
