Superdelegates explained

See this article. It claims that if Sanders, for example, wins the total regular delegate count in the nomination then the superdelegates will not tip the scales in favor of Clinton. The argument goes that to do that would divide the Democratic Party to the point of losing to the Republicans. Clinton has pledges for the vast majority of superdelegates. But it could happen that way, even though to date it has not come to that. Given the DNC's utter bias on display in this race so far, and the assured support of Wall Street for establishment candidates, I wouldn't be surprised of this scenario.
