I highly doubt Savage would have to guts to do it in O'Reilly presence. .....like Laura did.
I really doubt Savage is intimidated by O'Reilly. Boortz easily got O'Reilly to lose it and call Neal "a vicious son of a bitch". Savage could make O'Reilly cry, but neither is going to call during the other's show. He was mentioning how all his calls in the first part of the show were about this thing with O'Reilly. I think it's because those are the brawls you really want to see. I'd like to see Moore vs Savage (just to see Moore destroyed).
I like how Hannity tries to go after libs, but he just misses so many opportunities it's embarassing. It's probably why he surrounds himself with all those papers; to have his cheat sheets ready. Savage just goes balistic, which is probably what many people like about him (hence all the O'Reilly calls). Hannity has a good heart, but it's a shame he uses the same arguments all the time and is outmaneuvered by a lib who's heard them.
The way Savage makes fun of Rush is "Boy, those Democrats sure are terrible, and boy, let me tell you, those Republicans really are swell." His "Hannity" is simply, "Hey, there buddy! My good friend! Hey, good to see you buddy!" It's funny because it's true.
