I'm arguing no such thing. I'm stating that Rush is not a politician the same as Keith Olbermann is not a politician.
That's not quite what you said.
He has no vote. He authors no policy. He establishes no platform.
The first is supposed to be true. It's what a congressman said to start this whole thing. Rush exerted enough pressure to get him to apologize for saying it. So he may not have a vote, but he wields enough influence that the people who do have votes are afraid to say so.
The second is mostly true, in the sense that he doesn't write everything down in a fixed form that you can refute point-by-point.
The third is absolutely not true. No matter how much you pretend it is.
