Why am I not surprised at all with this? I have heard and known many high profile Right Wing commentators who have said that there are some in their business who only play the 'Conservative' card simply because it pays the most. The first name that always struck me was Savage.. this is just more evidence.
I listened to his very first radio program on KGO in San Francisco, might have been 94 or so. He was guest hosting. His schtick that he uses now wasn't there. He was soft spoken, expressed probably mildly right of center views, and that lasted maybe the first few shows he did.
Then "Michael Savage" as we know him came out. It's schtick. It's an act for all of them. They don't talk that way at home, except maybe Hannity. I have heard that Hannity warts and all, is Hannity all the time.
They are entertainers. Enjoy their shows or not.
