By and large, they are--but not sufficiently upset that they'll cheerfully hand the country over to the Dems.
The ones that are that upset are, by and large, the people who didn't bother voting for him in 2000. And they're PO'd because, while they get an occasional goodie, he doesn't OWE them a damn thing.
It clearly is. Rush is the voice of the base.
Actually, he's the voice of Rush, and nobody else.
"Rush can gripe all he wants. He did the same thing with Bush's father and pumped up Buchanan. Holding his feet to the fire, you know, and all of that."
And look what happened to Bush's father. The conservatives walked out on him. Just like what's going to happen to W unless he stops stabbing his base in the back.
If Rush is willing to do that again after what eight years of the Clintons did to America, then he is not actually engaged in supporting conservatism. He would merely be engaged in building the Limbaugh Personality Cult at the expense of actual progress on conservative issues.
