Even if he hits all those marks and wins all those states. He still loses. He needs to SURPASS those expectation. Once we get final delegate counts, I'll do the math to see just how improbable him winning is.
IMO it's definitely over for Sanders. Even ignoring that winning the nomination would be a miracle to begin with, the media will be crowning her as the nominee tomorrow. There's no chance of recovery.
I'll still vote for Bernie in the primary even though Hillary's winning literally every state from this point on (assuming I don't vote in the Republican primary, which may be more worth it since there's actually contested races on that side in my area), but I'm cautiously supporting Hillary now. I'll probably vote for Stein before Trump.
