Neocon NeverTrumpers were never really conservatives. They were planted into the GOP to influence policy in certain directions, then left in a huff when it looked like Trump was not going to use them as any sort of policy gurus.
And yet most still don't have much to say about Pres. Trump's actual policies or appointees, other than Boot. They keep finding all these non-policy intangible reasons to continually attack him. It's all "he's bad", "he's abrasive", "he's this he's that". Something very weird is going on.
