Clicked on the embedded link. Not sure where they got their conclusions. What I saw was dittoheads and pinheads were both near the top in both areas, with NPR having a slight edge. It still demonstrates the point I was feebly trying to make. At some point in time (2007?), 36% of Rush's audience were college grads, and half were well informed. I'd guess a fair share could grasp satire. Especially when the host regularly reminded them that his how was a mix of irreverent satire and serious discourse. I suppose a fair share also thought satire was some kind of wheel and discourse had something to do with sex.
