Who's whining. We're the ones with 400 superdelegates. You guys are whining. The rules are the rules. If you don't like them, change them next time (and I would support you), but I hope Hillary takes advantage of every possible advantage, including winning with superdelegates if the need arises. If you don't like it, file a lawsuit. Don't vote for her. Riot. Do whatever you want. But she has a right to look out for her self-interest and I hope she does.
She won't do that. She is perfectly aware that if she wins only thanks to superdelegates, media will repeat until November that she is illegitimate and that the party stole the victory.
Electorally, the result would be calamitous for both her and the party.
