“…the racial and ethnic isolation of Whites at the zip-code level is one of the strongest predictors of Trump support.”
Carpet bomb all the mobile home parks, there would be little collateral damage!
Actually you're wrong there Mic. The Milgram social psychology experiments show that the authoritarianism psycho-pathology, so notably evident in Trump supporters, has no predictable traits, such as, education, race, religion, political affiliation or socio-economic status.
What Trump supporters do share in common, based on the evidence of social psychology, is that his supporters fall almost universally into what Milgram called an "agentic" state in which a person allows another individual to take responsibility for, and dictate the direction of, their actions. They rationalize and attempt to validate the actions of their authority figure. You see, for example, Darth Omar and Anatta making these rationalizations consistently.

You see that very obviously in the hard core Trump supporters in how they abdicate responsibility for their own actions and let Trump dictate those actions. As long as Fearless Leader (in this case Trump) dictates the direction of those actions then that is the direction taken.
This is hardly new. All sorts of historical figures, past and present, have driven their nations over the cliff followed in lock step by those afflicted with authoritarian psycho-pathology. Chavez, Castro, Mao, Hitler, Stalin to name just a few have blindly followed their Pied Piper as long as they don't have to take responsibility for their actions.
Trump has proven to be a master at manipulating the authoritarian psycho-pathology and that's what makes him a scary demagogue.
