I can't see her as a VP- she's too controlling and wants too much control. She'd completely overpower who'd ever pick her. Dean would be a fool if he picked her- and I don't think he would. A fool like Gephardt or Kerry would, though.
I'll admit it's difficult to see her as VP, but remember that it is primarily an appointed position, an easily attained position, her specialty. Knowing, I'm sure, that she knows Bush will be re-elected, her long-range plan to position herself for '08 would be running now as dem VP.
Dean is not likely to do it, but who would he choose? Graham and Edwards have been mentioned as possible VPs in order to get Southern votes, but I personally can't see Edwards bringing in even his own home state of NC. As for Graham, I've never understood how anyone could vote for him even as dogcatcher.
