I thought his show was very entertaining for its first few years. It was only when the usual political tensions between the Republicans and the Democrats extended to the White House during the Clinton administration that Rush began to take himself seriously and proceeded over time to become a caricature of himself.
Now, the act has worn thin and he simply sounds like an angry old man.
Bingo! He's either an angry old man, or he's grasping at straws with the thought that being increasingly outrageous will translate into reversing his ratings and revenue slide. 25 years ago as I traveled around the country in my work, Rush was a regular part of my routine. I'd listen to him wherever I was in the car between appointments. But, at least to my ears, he became increasingly strident and "full of himself". And I agree, "its not just Rush". I think talk radio in general and political talk in particular has had a fatigue factor that's finally having a negative impact on the genre. In the case of political talk, I think the fatigue factor is excacerbated by the gridlock and rancor in Washington.
I can't say that I'm happy about any of this. Being politically independent, I used to think that having public platforms for both the liberal and conservative points of view would prove to be a good thing. But instead of civil and thoughtful debate (too boring, apparently), it degenerated into character assasination, name-calling, lies, and outright hate from both sides. If people are sick of it, no wonder. But I also agree that Rush and the other political talkers do have a hardcore following, so I personally don't look for political talk to disappear enirely.
But the one aspect of the decline of political talk I would welcome is the lessening of the amount of venom on the public airwaves.
