EVERY conservative caller gets a dozen callers like Kevin every week. They are full of generalities and will readily say that you are racist and that “everybody” knows that Palin said such and such, but when you push them to give specifics, they can’t because they are just useful idiots who are full of propaganda but no facts.
I think it's funny. Rush pushed and pushed for one example, and he was probably hoping for the Tina Fey quote, it seems to be the only one a liberal can come up with, when pressed. The idiot couldn't even quote Tina Fey properly.
