The superdelegate system was put in place in the 70s. Republicans also have superdelegates although they function differently. Superdelegates didn't tip the primary popular vote which Hillary won 16,914,722 to 13,206,428.

The media is not the DNC.

Day of primary doesn't add up to 3.7 million votes.

I voted for Bernie and I'm damn proud of that vote.
