At Swampland, Klein called it right:
I’m of two minds about how to deal with the McCain campaign’s further descent into ugliness. 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. But…every so often, we journalists have a duty to remind readers just how dingy the McCain campaign, and its right-wing acolytes in the media (I’m looking at you, Sean Hannity) have become–especially in their efforts to divert public attention from the economic crisis we’re facing. And so inept at it: other campaigns have decided that their only shot is going negative, but usually they don’t announce it, as several McCain aides have in recent days–there’s no way we can win on the economy, so we’re going to go sludge-diving.
