During the interview, he mentioned that he was on Salem Communications stations. Salem bills itself as "Reaching audiences interested in Christian and family content and conservative values on air and in print". The interview was quite good and is worth listening to.
The thing that perplexed me a little is his comment about Glenn Beck being on Salem with him. I've got nothing against Glenn Beck, even though I have some disagreements with some of the things he says on the air.
I was perplexed because, according to several things that came out during his rally in Washington, Glenn is affiliated to some degree with the Latter-Day Saints (the Mormons). That doesn't make him a bad guy (I have friends who are LDS and would treat me better than a lot of other people I know) but it raises some questions in my mind about Salem Communications decision to sign him.
