MTV, already so accepting of bisexual promiscuity and Pete Wentz's hair, announced this week that it will, for the first time in its 27 years, accept political advertisements, noting in a statement, however, that it will only take ads from a "legally qualified candidate" or a "nationally recognized political party." Yesterday, New York radio host and conservative pot-stirrer Curtis Sliwa informed Independent candidate Ralph Nader [relevant bits at 7:45] that only Barack Obama and John McCain are invited to buy airtime for what will no doubt be embarrassingly unhip ads on MTV. "This is news to me," Nader said, calling it "political bigotry," and threatening, "We may have to litigate this."

But is it all just a big misunderstanding ... on Sliwa's part?

Reached for comment, Nader campaign spokesman Chris Driscoll tells Radar: "We're looking into it. We haven't crafted a response yet but undoubtedly will." He adds, "We feel that the American people have a right to hear from their candidates. We don't ration the number of brands of toothpaste, we don't ration any kind of product, so why would we want to ration people's access to hearing their candidate?"

Jeannie Kedas, executive vice president of communications at MTV, says she's trying to clear up some confusion. "It was misreported. We would consider and accept third-party advertisements on a case by case basis," she tells Radar. "You might want to tell Ralph Nader."

For his part, Obama might welcome Nader ads during Date my Mom—assuming the increasingly irrelevant consumer advocate can scrape together the cash. (So far, the campaign has only produced Web ads.) The newest Los Angeles Times/Bloomberg poll found that the inclusion of third-party candidates Nader and Libertarian Bob Barr actually helps Obama. And despite what the experts are predicting, Obama might need it to counter the McCain offensive we're going to call "the Montag effect."
