The way I had it put to me is that for the republican party, their "devil" has always been the presence of Satan in everything, whereas with the democratic party, their "devil" has been people being stupid (this is why they believe everything is wrong with the country) so as a result, they have an extreme prejudice to anyone they believe is being dumb and will aggressively align with whatever viewpoint they think "smart people" believe, even if it is ridiculous and absurd.
