Yesterday, Chris Bowers explained why it doesn't make sense to start tallying up how many superdelegates won candidate or another "has." It's a good post, but to boil it down to a sentence: These are unpledged delegates and they're allowed to change their minds.

I would also, however, note another factor -- very few people know who the superdelegates are. Indeed, I heard an anecdote the other day about a politician who was wondering whether or not she was a superdelegate. The person who related the anecdote to me didn't know either. Well, I knew that she was, in fact, a superdelegate but I understand the rules -- but at this point in time the rules are so poorly understood that some superdelegates don't realize they're superdelegates.
