We may see a viable third party emerge.

Since the democrats have the choice between a criminal, a socialist, and party self destruction, we will see a viable third party candidate crop up. If they play the criminal, they alienate berniebots. They play Biden, they alienate berniebots and some shillary supporters. They play Bernie, they lose because he's so far to the left. They won't win.

Because the dems are in such dire straits without any strong leadership, the party will likely implode, and a viable third party will likely rise up.
