He's like the nerd guy who constantly whines about the popular kids and the captain of the football team - whom he has never met. At one level, he might actually have a point, but it's hard to sympathize with someone who obsesses over trivialities. He has such an obsession over Bush, conservatives and Republicans, it's hard to imagine an actual normal conversation with him.
I don't think he's any more an idiot than the Hollywood types who keep lecturing us all about things we already know about, but offer no solutions except who is to blame for it. The same problem afflicts most of the Democratic Party. If a Democrat gets elected to the White House in 2008, we'll have four years of continuing to hear how everything is still the Republican's fault, even though they'll be in the minority - they don't have any other songs to play.
