When I look at this issue I see two things: First, that this super -delegate system was initially established to forestall the nomination of a candidate that can't win the general. And second, this system has been co-opted by the DNC to basically allow party insiders to coronate whomever they choose(or at least stack the apparent vote against an insurgent candidate early on in the process to keep the party in line).
In this case I believe that there is another potential outcome-to split-up the Democratic and Republican parties. I believe that pre-pledged delegates will force the progressive democrat to vote their conscience in the general election. Bernie supporters will fracture the democratic party by voting for Bernie and the "anyone but Trump or Hillary"  voters will fracture the Republican party when they vote for Bernie. This, I believe will in essence be the defining moment that the Independent Party becomes bonafide. As for me?, a lifelong Democrat NO LONGER!
