This is going to be fun to watch.
If they do this they can stop the Republican from gaining a supermajority in the Senate, and while I think they still lose the house they can keep enough to be a thorn in the side as they now are in the Senate. But the socialists will run their own candidate and may get more votes in the General election than the Democrats.
If they don’t do this they will be in a better position to recover in the long run but with Bernie as their official candidate they will be crushed in the legislature.
The Bernie Bros have said if he doesn’t get the nomination, Milwaukee will burn. So its not only popcorn time, but roasted marshmallow and hot dog time
