C: Basically, Sanders caved to the very party that didn't support him and that he didn't have a chance in heck to win their nomination. Rather pathetic if you ask me. He's not doing what's best for his supporters, he's doing what's best for the party. He's become 2 faced and even though the boo's were against Hillary, they should have been against him for not standing up for what he told his followers. After the events of the weekend, he owes the Democratic party nothing. The emails show they supported Hillary and would do whatever it takes for her to win and for Sanders to lose. He really should be angry and upset and let the party and his followers know this instead of turning his back on them. He's a sell-out!
