Obama touched on a similar point a few years ago. He noted that he wasn't surprised that a populist attracted the right referring to figures like Johyn Wayne, but he was surprised the person they saw traits like honesty, hardwork and accountability was closer to Richie Rich.
It doesn't surprise me. When people are racist, they want to believe what feeds into so Trump only needs to sell them lie that he's that guy, the guy that will drain the swamp and punish the corrupt.
