Sanders is grasping for air at this point. He won like 10 states. If he got the super delegates for those states, he still won't gain that much to overtake Hillary's pledged & super delegates.
And they didn't do that for the last elections. Why know? I really dislike that about him. You're new to this party. Don't come and change our rules, policies, etc. Idc if u disagree.
EDIT: Wait not him wanting super delegates in states Clinton won. His argument is basically what Clinton is winning on right now. Such a stupid comment
