These positions aren't contradictory; there are a ton of people that voted for Trump not because they're Nazis, but because Trump's terrible ideas about race and sex are just not very relevant to them. They just didn't pay attention to that aspect.

Eventually, people realized that Bush II was a bad president, and that came from the slow, unavoidable accumulation of facts. People that showed up at the ballot box (but not to rallies) for Trump will eventually come around when they see how incompetent he is, how often he lies about easily debunked things, etc. The jokes and insults won't be a productive part of this process.
