Right, I'm 64 and have listened a bit to Beck, although a little too zany for me, I certainly respect his rallies for the troops, very well attended. You have to get used to listening to him to realize where his core beliefs are. He does draw the 20s something crowd into their 30s.
I'm not quite in your demographic group, but REALLY LOVE Glenn's show when he plays an audiotape in Arabic with a simultaneous "translation into English". (The Arabic devolves not at all into what the Arab is saying).
(Or "interviews" with Steven Hawking, who lapses into street F$#*$& jargon after about a minute).
I guess I'm addicted. It's been on for at least three years that I know of.
