Well, I sure hope those predictions are right, the pendulum swings, and the MAGA movement drops dead. I am inclined to think it will, as I think this kind of collapse is a bit like waking up from a dream. People's bandwagon mentality allows them to follow a course without thinking until they jump off and pretend they did not realize what they were doing. Once the shift occurs, nobody will turn out to have been one of the bad guys. Everyone was in the resistance.
But I suspect there will be a mess for a while, and the beast will only be dormant, waiting to be re-awoken by the next demagogue when enough people have forgotten enough history.
