PA, New York, Illinois, Ohio, Georgia, New Jersey, and Florida. You're right that he struggles with Florida, and he'll struggle a decent amount in NY because Wall Street has a lot of pull there. But if he can up his black voter game and open up PA, Georgia, Illinois, NJ, and NY nad up his union game to do well in Ohio he has a more than even shot at taking enough delegates to a contested convention. Which is not optimal but if he's given a shot to barter with the party, take someone in who's more conservative as his VP for the nomination, if we're looking at Candidates maybe someone like Ryan or Klobuchar to attempt to bolster himself with the Biden crowd. I mean I'm sure he'd rather have Nina Turner but I don't think the establishment would let him have that choice without outright winning.
