William McGurn, of The Wall Street Journal, had some thoughts on this as it concerns NeverTrumpers [emphasis added].

Give the Never Trumpers their due: most do not shy away from the implication that anyone who would vote for Mr Trump is as low and base as he is. Their problem is that the argument doesn’t seem to be having much traction with Republican voters. …

One reason may be that the argument about morally corrupt GOP voters is not really an argument. More precisely, it’s an argument Republicans typically hear from the left. Instead of weighing the prosaic facts—i.e., the practical ramifications of having Mrs Clinton sitting in the Oval Office versus Mr Trump—how much easier it is to try to end all discussion by pronouncing the GOP nominee repellent.

Because forming a rational argument on the matter is as repugnant to NeverTrumpers as it is to Progressives like Clinton and Obama (and Reid and Schumer and Pelosi) and to Democrats generally.

This will only get NeverTrumpers Clinton as president.

It’s hard to believe these folks—grown, adult, rational human beings all—don’t know that.  Maybe NeverTrumpers just don’t care one way or the other.  Maybe they’re just abdicating their responsibility by hiding behind their demand for purity rather than doing what’s least damaging.  Or what’s possible.
