Palin has the Democrats, specifically Obama's campaign staff, completely rattled. McCain was supposed to pick a nice safe old white guy for a running mate, and then go down in noble defeat. He failed to play by the script.
The Dems were completly blindsided by the pic, which explains the whole "out of nowhere" meme. If they had been paying attention, they would have noticed that Sarah Palin was in the top three pics for the right wing bloggers.
They are rattled and flailing which explaines Obama's remarks earlier. Either he is a sexist pig, or he's too stupid to see why his remark is offensive. Or my personal chioice, he's an elitist snob.
Xavier goes with the sexist pig theory, and writes better than I can anyway.
