A standup comic once joked about his inner monologue while rubbernecking through the scene of a car accident. First the serious reaction: "Oh! How horrifying! How awful!" Then the morbidly gleeful: "Cool! Is that an arm?" Watching the Republican Party implosion and subsequent bloody flailing has become my favorite spectator sport. "Wow, the Republican Party is really, really horribly mangled," then, "Cool! Palin's making an ass of herself on TV again!" How screwed are the Republicans right now? Put it this way: the sanest contender for party leader is named "Bush." Yes, Bush: a name that proved to be even less popular this year than the name "Hussein."
