Heck, everybody else is talking about it. Even Greta on Fox flat out asked Her tonight.
Sarah said "no".
There is a great picture of Her in a T-Shirt top, with what looks like a world class set, that was taken at Belmont. That is where the rumor stared.
I think most of the time she delibertly wears clothing articles that tend not to accenuate her assets. She said as much on Greta, but that look she was giving the camera said "I know what you guys like".
I'd give a hefty contribution to any campain she chose if I could be "Mr Palin" for one hour..
