Glenn Beck is an entertainer which is why he is so popular. None of the guys you mention have the charisma or personality to be a Glenn Beck. If they did.... they would doing it.
I saw Ken Ham speak in person just a couple weeks ago, he's great! But totally different from Glenn Beck.
lain: Yeah, I like Charles Stanley & John MacArthur but they aren't very entertaining.....unless you really are interested in the subject to begin with.....which I usually am.
