Atrios describes perfectly, in my opinion, the Democratic frontrunners:
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.
I still like Edwards, by the way, for those of you keeping score.
UPDATE: Ezra Klein agrees that this is a good distillation of Edwards’ message, but responds, essentially, “Great. How?”
