Penn Jillette is a Libertarian, not a liberal.
I watched the MSN program and Penn said that personally he really did not like Bush or his policies, but Moore was SUCH an lowbrow obnoxious jerk that everytime he saw the guy he had a urge to choke the daylighs out Moore and felt himself moving "way to the right" whenever Moore starts yammering.
So I say, keep up the good work Mikey!
