How many of his books did you read?
I've heard him since the day he came on the air at WABC in New York, way before he was syndicated and streamed across the country. He would come on after Rush and basically parrot Rush's show for three more hours.
As we say in New York, "he ain't never shown me nuthin'".
I also quit watching the TV show because I couldn't stand his cliches and watching him getting his clock cleaned by stupid liberals like his co-host. The only time I ever tune in anymore is when Ann Coulter is on, because she has the mental agility to hold up our side and defend pretty-boy as he fumbles around for a clever retort.
But he's popular (like rap music is) so he'll be around for a long time. Let not your heart be troubled.
