The point of "grand bargains" between the parties isn't to get something done, the point is to get something done in a way which leaves no one for voters to blame. It's accountability free legislating. Villagers love this, because they hate this whole voting thing and just want Bob Kerrey and Alan Greenspan to rule by fiat in order to make the poor and middle class suffer as much as possible without any resistance, but it means the rest of us are out of luck.
