FWIW, Trump has all of the characteristics of a very bright eccentric individual, untethered by politically or socially correct expectations. Many people like that have off-center warped but well formed senses of humor, and they tend to be opinionated. I’d guess his IQ is massive. Calling anyone like that dumb never turns out very well.
