What radio stations or tv stations is he on?
his site is http://www.glennbeck.com
Lots of radio stations (I've heard him say they're the third most listened to radio show...but I don't know if he's talking about a particular demographic), you can probably find a list on his site.
He's on TV twice nightly on Headline News (eastern time he's on at 7 and the show repeats at 9.) We're all amazed that CNN is letting him say the things's he's saying on the air.
