Ingraham went to the other side years ago. Remember she was smitten with Mitt.
She and Coulter are just pimping their books. They know the only was to sell them is to throw read meat to conservatives. But if you listen to them both, they are just inside the beltway Washington opportunists that wrap themselves around conservative principals just to shill themselves.
The only two I listen to and respect are Rush and Levin.
I'd add Savage to your list and I do agree with what you said.
