I've not listened to Prager much at all, but when I see him on television he seems very likeable. I saw him on Larry King's (awful) show with some other talkers and he handled himself well, especially when confronted with that idjit Ed Schultz.
Prager is awesome - I liken his show to what NPR would be like if it had a conservative bias, integrity, and clarity. Of his 15 hours a week, all of them are usually interesting. He sometimes has authors on of non-political books and it's a great change of pace. Keeps things fresh. Prager rules it!
One of my other faves, Mike Medved, is doing a live broadcast from here in Las Vegas Monday the 26th at a major hotel/casino. I look forward to going down and checking it out!
