Republican’s cheat, most people are aware of this in one form or another in the pre-Obama years Democrats often just fumbled the ball while the Republicans did their cheating.

But here is the thing that might steal it away for Hillary this year 9% of Superdelegates are lobbyists who are not beholden to the Democrats but only to their special interests.
