It will never stop during our lifetimes. Old people used to rail against FDR, and some still blame Nixon for today's problems.

It's human psychology. They get a bad thought that they know is unacceptable. They have to get that bad thought out. Solution: blame The Other. It's worked for thousands of years. Think of the preacher that constantly warns of the evils of homosexuality, and that you should never go down to that truck stop on the highway because their bathroom is where all the evil men are to be found. Blaming the Trumpmonster will never go away. It's too emotionally fulfilling.
