"Their strategy is simple: you throw crap against a wall and then giggle as the media try to analyze the putresence in a way that conveys a sense of balance: 'Well, it is bull-pucky, but the splatter pattern is interesting...' which, of course, only serves to get your perverse message out. I really don't want to be a part of that.

It is appropriate that the prime vessel for this assault is Sarah Palin, whose very presence on a national ticket is an insult to your intelligence. She now has 'credibility,' we are told, because she managed to read talking points off notecards in the debate last week with unwitting enthusiasm."
It goes through the idiocy that is the attack on Obama based on him knowing Bill Ayers, and the rest of the loony tinfoil hat theories the wingnuts are tossing about. The entire thing is worth a read.
