Actually, hyperaggressive gay liberal Sascha Cohen went after Ron Paul in his latest film a couple of years ago.
Cohen did a series of "setups" with famous people in which he tried to ambush-interview them (rating a loud and impatient "FO" from Harrison Ford) or create some really embarrassing guerrilla-theater encounters.
Think of a Michael Moore film and then gay it up about 9,000,000% and you're there.
For Ron Paul, Cohen set up a hotel-room massage/gay-seduction tableau. Paul was polite, but when he realized what Cohen was up to, he got up and left like a normal person.
I didn't see the whole film. I left not too long after the scenes with Ford and Paul.
