The explanation goes like this. White nationalism is a majority position among our white population. The majority of white voters are single-issue voters for white supremacy. They don't care that he's an unimpressive German pedophile as long as he does things that enforce white supremacy.
What I can’t get my head around is that someone this utterly unimpressive gets to be a dictator. I mean, I’m sure I’m missing something and it’s just me who can’t see it.
