I'm really not surprised. I think the "old school" liberals thoroughly dislike the hold the "MoveOn.org" type folks have on the Democrats. They like the money, yes, but they don't want these guys calling the shots. An opening like this is the chance they've been waiting for, I would think.
Money. It’s the motivation, and MoveOn has it.
Stop acting like a fringe-wacko and the money dries up.
The Old School libs hate that, but China only has so much to give them. :)
