I do not usually listen to replays of Rush's podcast, but today I did, and heard his analysis.
The paragraph you posted above, hits the proverbial nail on the head.
Calling them the "conservative intellectual Never Trumper movement," is overly generous however.
Results count, not pious self-serving pointy headed noses in the air.
Since Rush and Levin have used the term #nevertrumpers, this week, I'm still good with it too.
I vow to stop, when all name-calling by #nevertrumpers ceases.
