This list will begin with the more benign reasons for Trump’s intransigent support. As the list goes on, the explanations become increasingly worrisome, and toward the end, border on the pathological. It should be strongly emphasized that not all Trump supporters are racist, mentally vulnerable, or fundamentally bad people. It can be detrimental to society when those with degrees and platforms try to demonize their political opponents or paint them as mentally ill when they are not. That being said, it is just as harmful to pretend that there are not clear psychological and neural factors that underlie much of Trump supporters’ unbridled allegiance.
