Well, I seem to translate his bottom line point being the same people ie. Noonan etc. that would criticize Trump for “perceived” behaviors that someone like Reagan would get from them a complete pass.
I happen to agree with that.
Also I would agree that those very same people feel “disdainful” toward Trump and those that support him. Not hate but a sort of derision borne of self righteous arrogance and conservative puritanism.
