I imagine he has his health to think about right now.
By the way so was Dr. Michael Savage out there defending Trump and he was for Trump long before Rush ever thought about it. Remember Rush was strongly in the corner of Ted Cruz before he finally came around.
IIRC Rush never endorsed Cruz or Trump out right. He gave both of them kudos. I don’t recall him every really saying on air a preference for one over the other.
Not only was he in Cruz’s corner, he was also talking up Rubio! Denigrated and pretty much made fun of every “Trumpist” that called in. Caused me to drop my 24/7 and quit listening to him until after the election. All that said, I always like listening and pray God heals him.
