I'm starting to think all of this is a show. They get the Bachmanns and Palins to go act extreme right nutty to keep the fringe loonies happy and voting republican and then the establishment gop distances themselves from them to get the more moderate republicans and some independents to vote for them.
It's called a useful idiot, and Palin has been one for the Repubs for several years now.
As for her speech - big deal, she's making a joke in front of the NRA. People need to lighten up.
