I didn't read past your first paragraph because it is patently false. Hillary won with our without the superdelegates, received more than 3 million more votes than Sanders, and the race was never close past New Hampshire.
How can we know that? Because that's precisely what happened in 2008. Hillary had tons of superdelegates lined up behind her when the primaries started, but then Obama got more votes, so the superdelegates switched.
