NeverTrumpers never wanted to fix anything, ever. That requires work and they won’t do work and know no one who will. Implementation of anything they claim to want is actually counterproductive, because it would eliminate the ability to talk about how virtuous it would be to have that concept implemented.
NeverTrumpers are repulsed by anyone who actually could stoop to “do.” They use the opportunity to sneer they could have done better, but it is only posing. But they look credible when posing because they have spoken of dozens of virtuous concepts over time and none were “able” to be implemented. If one got properly implemented, people would then wonder why more weren’t implemented, and that would mean a lot more work would have to be done, which they don’t want to have to do.
They bring down doers because they make the posers look incompetent.
Posers vs doers is a great way to frame it. The Romney vs Trump issue is a perfect example.
