He mentions the start of talk show popularity with truck drivers, I forgot about that til now but noticed it at the time, it was a surprising phenomenon. It really started with working class like that but then it moved to lots of white collar types all of a sudden uncloaking as conservatives, as if they had been afraid to speak before, they would have "Rush rooms" in restaurants for lunch where they played his show while people ate lunch. And he got popular real quick with the Wall street set talking economics. It was really strengthening of the Reagan coalition. The big difference from Trump: was NOT POPULIST. One thing that really hit me listening to it in the car from time to time iss how he would always have one or two callers selected for lecturing, they would call in and profusely profess their fandom, try to get approval, and he would disagree with them and tell them how they didn't have it  exactly right and correct them. THE genius "with one arm tied behind my back" NEVER had experts as guests, always people who expressed fandom of the genius who had to be further instructed, not as smart as Rush, like a preacher would do. So he was like Trump in some ways, different in others.
