There's never been a VP pick who was a “miracle”. Most VP picks don't even bring in their home state if it isn't in the party's pocket already. Instead, VP picks can help a bit if they rally the base, get people to start paying attention to the ticket, and prompt party members to open their wallets and contribute. That's where Palin will be a success. She won't send McCain's poll numbers through the roof, and certainly not enough to cause a compressed tracking poll to change in a single night. But she will help the ticket in the long run.
BTW, Rasmussen's four point Obama lead now includes polling from the three best nights the ‘Rats will likely have. Hillary's speech, Bill's speech, and Obama’s speech. Those three nights produced a “miracle” of four points collectively.
Does anybody know the music used to introduce her in Dayton??
It was good, but unfamiliar-- to me sounded like a cross between Star Wars and a Scottish march?
