I think it may have to come to that.  Neither candidate will win based on pledged delegates, and so the superdelegates have to decide how to choose.  To argue that they should just replicate the pledged delegate vote is silly--if that's how they should choose, then there's no need for them at all.  Instead, they're supposed to make a decision based on who they think can win the GE.  And, that decision ought to based (IMO) on the popular vote and on who has won the states that really will go for the democrats (not solid red states).
