The (D)s are going to screw themselves again by pushing Sanders out in favor of someone not-Sanders. Bernie fans will not vote in protest. And we will have four more years of corruption. USA! USA! USA! *sigh*
I'm not sure, I think you liberals definitely really hate trump so that might help you guys out. Bernie has been aliening white women (who normally hate trump), bernie wasn't getting the black vote, and bernie was under performing youth turnout in the last couple of primaries and caucuses. Furthermore bernie really burned florida to the ground praising castro and being critical of israel. Cubans and jews are two huge demographics in florida. Lastly, it would have been very easy to mar bernie with the socialist label.
Also all of the success of liberals in 2018 was not due to AOC type policies, but moderate democrats winning in purple states.
So in the end, I think i'd rather have trump run against bernie than biden.
It really comes down to how pissed off the bernie bros will be.
