Which superdelegates?

Obama is now leading Clinton in every category of elected superdelegate -- Representatives, Senators, and Governors. He trails in Distinguished Party Leaders (ex-Presidents, ex-chairs of the DNC, ex-Speakers, etc.), by 10 to 4, and in DNC members by 145 to 119. The DPLs are small numbers, so the DNC members are the real meat of it. So Obama is leading in pledged delegates and in superdelegates who were elected to their positions. How "unelected" can the superdelegates choosing the nominee be? We'll find out.
