Gross. Dems are asking for trouble here. It's blatantly obvious that superdelegates have outlived their usefulness (actually, they've never had any to begin with.)
If they're ever so desperate that they're willing to disregard democracy and cause a massive clusterf**k, they could just unbind the delegates altogether. So I really don't see what purpose the supers serve.
With the supers, the establishment has the power to save the party from a bad nominee. Yes, the supers have never collectively gone against the pledged delegate winner, but if the democrats were about to screw themselves over in what they think is a competitive GE (if you're going to ask why they didn't overthrow Mondale, that's probably because they knew Reagan was unbeatable.), the pressure would be on the supers big time.
With unbinding everyone, you have to go through the trouble of actually changing the rules. With that, the "dangerous democratic winner" would do what they could to stack the committee with their members, like Trump did to a point (although there was some establishment anti-unbinding people) and the attempt to change the rules could easily fail. With the superdelegates, there's no rule change needed. You already have the unbound delegates. All they have to do is vote how they need to in the roll call vote to save the party.
In fact, there's nothing stopping the supers from choosing Bernie, if they wanted to. Clinton isn't at 2383 with pledged alone (Sanders didn't formally submit the papers to suspend his campaign or release his delegates).
Ultimately, with Trump winning and Sanders coming way too close to doing so, I just don't think voters should be trusted to do what's right for the party at the presidential level. Dems should keep supers, and Repubs should have them. There's a check in the general with the actual real life electors that are free to overturn the actual PV in all but two states (a bunch more states punish the electors for doing so, but only two actually throw out the votes), there's no reason a similar check shouldn't be done in the primary. The founding fathers had the right idea when they made the presidency an indirect election, and this year shows it.
