Never Trump Republicans seem to fall into one of two groups
(1)Opportunist Jerks: Take for example, The Lincoln Project. There is nothing ideological about them at all. They are career propagandists and PR people who correctly realized they can make a lot more money being anti Trump than pro Trump . Their ads have zero substance and basically just say “We hate Trump” Most of their ads are so devoid of substance that you can take the exact same ad, flip the names and a few pictures and use it as an anti democrat ads (they almost always run anti-ads. they almost never actually support any explicit policy) There is no way they can credibly claim they went after moderate and anti-Trump Republicans like Susan Collins because of anti-Trump ideology. Trump is also far from the first person they stabbed in the back when it suited their purposes.

(2)People who have a very one dimensional view of Trump: He is a not a nice guy. That overrides any and all good he may do. They don’t want to think or are in denial about any good Trump may have done. For example I asked a very prominent frum anti-Trump activist about the fact that had Hillary Clinton been president, last week’s supreme court ruling about Cuomo closing shuls would have been very different. In an answer that sounded like cognitive dissonance to me he answered that he never opposed any of Trump’s supreme courts picks. Technically speaking that may be true. Practically speaking it isn’t. Another frum anti Trumper vehemently denied to me that Trump had any connection to the Israel-UAE-Bahrain peace deal. Those people may not be liberal. They don’t seem to realize the consequences of a Joe Biden presidency.
