Thank you for confirming my long-held suspicion. You haven't sufficiently listened to the show to comment.
I have listened regularly since I first put Rush on one of our stations in Florida when EIB Network first started; we were a very early affiliate and we were credited with creating the "Rush Lunch" where a restaurant had one of its private rooms with Rush on speakers and listeners could come for lunch and a long listen to the show.
While not a professional Dittohead, I've always been a frequent listener as the show is really well assembled, even though it sounds spontaneous. I've used some of Rush's practices while training talk hosts in places like Puerto Rico, Chile, Argentina and the Dominican Republic.
Rush listeners know that comedy is a constant theme and Rush goes out of his way to make it fun. He even has at least one professional comic that makes material for him to run on the showand of course he is quite funny himself. Liberals just don't like being the butt of his jokes.
From my perspective, that's only a small part of the show for the most part. I would not say that comedy is a strong point of the program.
"Fun" does not mean "funny". That's my point in countering the idea that politicized talk shows are not entertaining.
Rush: currently approximately 600 stations, 30+ years on air
Air America: currently 0 stations, < 6 years on air
As I said at the beginning of this discussion, Air America was not entertaining; it was too intense and not personable enough. Somehow, every show sounded like a union meeting called to put forward a strike vote.
