My God, Hillary wouldn't want to win off the back of superdelegates. If that looks like it'll happen, then whatever happens, HRC won't be the nominee.
I think the point is that the choice won't be up to her because the superdelegates, realizing that creating 1968 redux would look terrible and damage her electability so that it would be worse than that of Sanders, won't actually back her if Sanders is the pledged delegate winner.
Thus, sure, the rules are the rules and she's entitled to take a victory via superdelegates. But it wouldn't happen, because the superdelegates wouldn't go through with it*.
* Should clarify: They wouldn't go through with it, unless some kind of John Edwards 2008-esque scandal befalls Sanders after the primary is over. Sure, if people vote, and a majority pick one candidate, and then before the convention some huge scandal come out about the presumptive nominee, then in *that* case the superdelegates could overturn the verdict of the primary voters. But otherwise, I don't see it happening.
