I know Popular votes don't matter in terms of reaching nomination but since NH primary, Sanders' supporters have been constantly complaining about Hillary getting support from superdelegates and allege that they are voting against people's wills.
But the current results show that Hillary has 3.9 million (61%) votes versus Sanders' 2.5 million votes (39%).

For caucuses, these numbers do not include Iowa and Nevada but include Colorado and Minnesota since they are actual votes.
For those who think the whole thing about superdelegates is unfair, well these rules have existed for many years and Sanders is fully aware of them, he is a superdelegates himself and he chooses to participate in the Democratic primaries. Besides he also gets superdelegates endorsements and are accepting them. It's just that Hillary gets way more superdelegates endorsements. So please STOP being so hypocritical by knowing these rules and accepting Superdelegates on one hand and complaining about the system on the other hand, geez!
