There's going to be Hell, and that's exactly what's going to cost them the election.
A few riots over some drug dealers and rapists and kid-fuckers caused the Democrats to completely tank in the polls. Their numbers went so low that they threw the kill switch and immediately reversed every policy and every position that they held if it meant putting an end to the riots. Nancy Pelosi herself was forced to march out on stage and demand that all of the rioters-- because they call them rioters now--be thrown into a prison.
That was a preamble. That was a pitiful, pointless tantrum, and it nearly cost them everything. What has the potential to happen is the mother of all tantrums. Whatever hope they had to keep a tenuous grasp on that boiling lid would be blown across the room, and there's not a chance in Hell that they'll be able to contain the rioters. They'd just riot. Again.
They'd go ballistic. They'd go batshit. They would create the Grandfather of all Clusterfucks and it would send Trump's approval rating straight through whatever is left of the ceiling. All he has to do is tap the mic and name a name, and with that single nomination, we'd be off to the fucking races, and there isn't a single thing that the Democrats could do to stop the nightmare-children that they've been cultivating.
The best hope that the Democrats have in this coming election is for their extremists to sit down, be quiet, and cause absolutely no problems. Do you think that they can do that, or do you think that their machine--the one that they just started to get under control again, before it destroyed them-- is going to rage?
