I think the bigger issue is that the right lives in a different world when it comes to facts. All information sources that aren't explicitly rightist are seen as unreliable. The media, the gov't, academia, even former Trump officials who speak out are just dismissed as being part of the deep state. If the right were libertarians or something, that would be one thing (bad), but what's worse is when Trump can just assert that he fixed the problem with pre-existing conditions, and people who support doing something about the problem just believe him. Or we could argue rationally about the costs and benefits of various climate-change-mitigation policies, but if some people just say, "nah, it's a hoax," where do we go?
