LIBERAL laugh-riot Al Franken is super unpopular with staffers at the Sundance Channel, which televises his Air America radio show.
"Everyone at Sundance hates him," an insider tells PAGE SIX. "For one thing, they're [bleeped] off that so much airtime is being devoted to Franken instead of independent film. He's got nothing to do with their programming." In addition, "He's such a busybody. He obsesses over every single promo and laughs uproariously at his own bad jokes. He thinks he's hilarious. And he's so bossy during the editing process."
A rep for Sundance had "no comment."
