Daily Kos speculates on Iowa caucus maneuvering, which might make one wonder why anyone cares about the Iowa caucuses at all. He’s outlined a scenario under which Kerry supporters might throw their votes to Gephardt in order to derail a Dean victory. And yep, that’s about the kind of thing that happens in caucuses.
I don’t think it really requires cell phones to happen, though; Kerry’s campaign can make that decision the night before and pre-arrange the votes instead of waiting till the last moment. They’d sacrifice up to the moment decision making, but they’d gain reliability.
Either way, it’s all a game of perceptions.
