Yesterday really closed any possible hope of a Bernie nomination at this point. He really needed to carry Ohio to maintain legitimacy given that Florida was a lost cause. If he managed to pull a few more Michigan upsets out of his hat he could have maybe made the case for some vast unpolled demographic breaking for him, but as it is he just won't get the votes.

Really, the only way Bernie ends up with the nod now is if Hillary ends up in jail, and that's just not going to happen. David Petraeus is still a free man, and nothing Hillary has been accused of is even close to what he did.

He's extremely unlikely to get the nomination, so he's probably not going to choose to run with anyone.
