One part of them acknowledges President Trump's manifold accomplishments, in particular his two SCOTUS victories, and will vote for him in 2020. The rest have or will let their mindless hatred of Trump the man drive them out of the Republican Party or out of conservatism altogether. Victor Davis Hanson:
The character assassination of Brett Kavanaugh by unsubstantiated rumor and gossip put Never Trumpers in a bind, or rather split them in two. Kavanaugh was nominated by the hated Trump, but his record and endorsements by the Heritage Foundation and the Federalist Society mainstreamed the choice.
[. . .]
To destroy a judge like Kavanaugh reflected that the New Left’s hatred of Trump had always been incidental to its essential loathing of conservatives in general. For a remnant group of Never Trumpers to oppose Kavanaugh, then, reflected the elevation of their own personal hatred for Trump over the critical elevation of a principled jurist to the Supreme Court. Supposedly, Kavanaugh was soiled by a Trump handprint, and therefore it was better to have a more liberal court than see Trump get any credit for taking the court in a direction only previously dreamed of by conservatives.
Never Trumpers had always assured their former conservative colleagues that Trump would either fail or prove liberal. But he has done neither. And as far as his demonstrable crudity and uncouthness, the hearings showed that the Democrats were far crueler and crass in deed than Trump was in word. So perhaps half of the small minority of Republican Never Trumpers, in horror at the Antifa tactics of the Democrats, retreated to the old adage of “hang together or hang separately.” Those who doubled down by joining leftists in opposing the Kavanaugh nomination revealed that they have crossed their Rubicon and now are either orphaned or unabashedly part of the new progressive Democratic party — at least until their useful obsequiousness no longer serves current progressive agendas.
