This article by Ezra, as much as anything short I've seen, explains why I intend to vote for John Edwards.

Atrios's oft-quoted campaign summary rings true for me, too, and since blog posts are supposed to have a quote, here it is:

Obama: The system sucks, but I'm so awesome that it'll melt away before me.

Edwards: The system sucks, and we're gonna have to fight like hell to destroy it.

Clinton: The system sucks, and I know how to work within it more than anyone.

3m20s parody video from National Lampoon makes some obvious jokes, but you can't help but get the feeling that the people described in the video really do think that's how it ought to be.
