Sanders was robbed
No, Sanders capitulated to Hilliary without putting up a fight.
It was obvious he had been shafted by her yet he just slunk away with his tail between his legs and barely a whimper so imo he has to take responsibility for his failure to call out Hilliary for the crook that she is.
All his supporters knew that clinton was doing the dirty on him and I am sure they would have rallied around Sanders, had he had the balls to call Clinton out, and then Sanders could have pushed on to make a decent challenge against Trump.
By not standing up for what was right and correct he proved himself to be yet another weak "leader" aka puppet, and he got his just desserts.
He had the chance to do the right thing and he blew it.
