Not sure it's a laughing matter for conservatives, though. Yes, he is entirely ridiculous, but what does it say about the GOP that this guy has been one of their most influential politicians for over twenty years?
Keep in mind that as ridiculous as he may appear, he's still pulling down far better numbers in primaries than other candidates like Kucinich and Dean. I wonder how his numbers stack up against Edwards.
I don't think he's been one of the most influential politicians in the last 20 years though. He's been pretty much irrelevant since he was drummed out of office, other than appearances on the talk show circuit.
He said "their
most", as in the GOP. Within that field he has to be at least top ten for the past 20 years in terms of impact, if not top five. Even many Republicans credit him for the sort of "scorched Earth," "I'm willing to do down so long as I take that other bastard down with me" attitude that the GOP have been taking over the past decade or so.
