so I can't really judge. However, my mother, who was a right winger & loved Bill O'Reiley, accidentally tuned into one of Thom's shows. A few days later when we were talking she asked if I had heard of him. I told her he was one of our best liberal voices. She replied, "You know I don't like liberals, but I thought he was very reasonable." I damn near fell out of my chair!!
on edit: Everyone should read Thom's book "We the People: A Call to Take Back America." It's written in a comic book fashion & is basically a fifth grade civics refresher course, with a little more. Highly recommended!
