Well, it ain't over yet and who knows if they've even bothered to count absentee ballots which will probably be necessary before allocating any delegates, but... here we go.
The Big Winner: Edwards. While Kerry has more wins, Edwards won't be too far behind in terms of delegates.
The Small Winner: Clark. Whether or not he wins OK - close enough. Delegate count should be even.
The teensy weensy winner: Dean. He'll grab delegates in New Mexico and maybe Arizona. No big win, obviously, but at least slightly exceeded expectations.'
The Minor Loser: Kerry. No big deal, and it's going to mostly depend on how the media reports it. But, will presumably slow his Big Mo ever so slightly.
Other than Edwards, mostly a wash in absolute terms. Though, obviously, his big SC win potentially paves the way for a Clintonesque Southern Storm.
...just wanted to add - these are all meant to be relative to expectations.
