From Ezra Klein’s short but interesting interview with Elizabeth Edwards:

Ezra Klein: The message you seemed to be previewing on Sunday was that Obama’s a great guy, he’s got a great philosophy, really good ideas, but it’s in his head and not in his heart.

Elizabeth Edwards: Except for the ideas part, sure. His health care plan is slightly different, but in most everything else, he’s adopted what John had said before. I’m not saying he can’t have great ideas, just that so far his ideas have mirrored John’s.

Ouch.

Good stuff in there about social movements, too, relevant to this post.
