Point of fact: he only "lost his nerve" with regard to HRC being the alternative.
Oh, I definitely am pleased that a fair number of NeverTrumpers lost their nerve. But I was an unshakeably conscientious objector. I regarded Trump as the lesser of two devils, not merely the lesser of two evils. I could not conscientiously vote for him no matter what.
Anyway, America is in God's hands, not in Trump's hands as commonly supposed. (If you will pardon a metaphor, Trump's hands are way too small.) I would even go so far as to say that we are in God's hands whether or not we survive the things that will hit us in 2017 and beyond. (That is a supremely comforting perspective even if it is way beyond Levin's grasp.)
