Yes, this psycho/idiot dynamic is rather common. The megachurch preachers and christian fundies, the "alternative medicine" peddler and the facebook moms, the orange one and his fanclub, etc.
I have to agree with this one at least in parts: I see no way how the situation could improve without collapsing first, at least not in merica. Trump is just a symptom of a horrible system, and seeing how much it resists any change into the sane direction (like healthcare), I'd wager it will persist until the bitter end.
Maybe the actual civilized world will survive it, but climate change is still coming, shit's still going to hit the fan.
