@blatham,
Bernie's problem is that he's waited too long. He could probably have gotten some concessions from Clinton if he'd seen the writing on the wall and gotten out of the way.
What does Clinton really need from him at this point?
I have a feeling there will be a carrot and a stick for Bernie: Deliver the votes and the Clinton administration will smile and throw you some bones. Act like a petulant child, and the Clinton administration will smile and crush you like a cockroach.
