1) he screws up on the facts from time-to-time (obviously, if I can see these errors when all I do is check newspapers and cable news shows, then Savage needs to do more show prep). BOTTOM LINE: don't take everything that he says as the God's honest truth.
2) his self promotion has been sickning lately. I'm tired of hearing about how wonderful his show is. I'm tired of hearing about how everbody else on the radio is a sell out. I'm tired of hearing about all of his degrees in nutrition or his travels in the South Pacific (like that makes him more qualified to talk about domestic & foreign affairs?).
3) turning down the volume on callers and flaming them when they have no means of engaging him in reasoned debate may be funny from time-to-time, but this does not make him a genius...he's just entertaining as a hatchet man.
