I mean his cheerleading for Trump, complete with tights and a short skirt.
I seldom listen to Rush anymore, but ever so often during the campaign I would turn on the radio while driving and hear what he had to say.
Prior to the primary I don't recall Rush supporting anyone. I recall him going out of his way to avoid creating the impression that he was supporting any particular candidate.
After the primary he did the only thing that a reasonable person would. He supported the Republican nominee over the Psychotic Nazi hate witch.
If he was supporting Trump prior to the primary, that was wrong and he should have done it. If he would not have supported the Republican nominee after the primary, that would have been wrong, and he should not have done it.
