Most have been branded Never Trumpers and mostly kind of lie low on policy differences (perhaps) in the interest of making common cause - which is not terrible overall. I'm thinking of Patrick Chovanec.
I think a lot of Never Trumpers have genuinely become more liberal as a consequence of their new alliances anyway (for celebrity examples see: Tom Nichols, Joe Walsh)
In a very real sense, they were always trying to retrofit muscular liberal interventionism onto a conservative frame, and it was never really a good fit. IMO it's better to have them in our tent and talk them down from the really bad shit.
Yeah Nichols is this, I think. I don’t think he’s budged on foreign policy at all, however when I still followed him I recall him confessing that, in retrospect, he was never crazy about guns, abortion bans, or basically anything advocated for by the religious right
