Kerry people don't have much of a choice. It's simply do they want a liberal, anti-Gun, non-Spanish-speaking 20-year Senator from Taxachusetts, whose wife, apparently, has never trusted him with a joint account...
Or a conservative, non-anti-Gun, Spanish-speaking (far better than Bush) 11 year governor, with some years of Lt. Governor experience and some years of Vermont State House (legislative) experience.
Dean isn't perfect, but Kerry and Edwards supporters must realize the press, at least, if not the country, has moved right, and a very liberal man like Edwards, or fairly similar Edwards, is going to turn off huge numbers of voters.
Don't get me wrong, I think he'd make a fantastic US AG. He wants to be President.
The old story about Southern Democrats getting elected (a meme that works for Edwards + Clark right now) doesn't mean jack if the Southern Democrat in question is a progressive (Huey "Kingfish" Long, John Edwards, very left) rather than a more conservative Democrat (Carter or Clinton).
