Media bias? At least people like Rush Limbaugh and G. Gordon Liddy are reasonbly honest about their bias. When Dan Blather frequently says "Conservative (this), conservative (that)" but *never* says "Liberal (this), liberal (that)", that *is* a symptom of bias. (Maybe I should say "almost never", but I've never heard him describe anything as liberal.)
You'd probably call me a flaming conservative, but I *do* find it hard to sit through more than five or ten minutes of Limbaugh at a time. Too much "I am always right, I know it, you know it, I told you so" blah blah blah. Liddy is more entertaining, at least; for instance, he used to have Lanny Davis on for interviews, and has a lot of other interviews as well, some of which actually are on pretty neutral subjects. And he makes no secret of being a flaming conservative.
Sean Hannity is another pretty conservative talk show guy who doesn't blindly go along with party, Congressional, or Presidential spin.
But as was said elsewhere, there's a reason there's few or no national liberal talk shows. They just don't sell. It's not as if Clear Channel or whatever your media conglomerate is would refuse money; if shock jock Howard Stern can get on the radio, surely a flaming liberal could, if he made money for whatever network he was working for.
