The problem is that more people watched McCain's speech than Obama's invesco address and saw that McCain was no GWB. His oratory skills are not great, but his appeal to moderates was tangible and his condemnation of the GOP for their actions over the last 8-12 years was another bone to the Indies.
I think the McCain = Bush strategy is a losing one, because when McCain is on a big stage, like the convention or presumably in the debates, people are not going to see that except for people who are already voting for Obama
Some of us knew it was a brilliant pick the moment it was made. I'd say it was the same group that knew Biden was a dud pick the moment it was announced.
Democrats have a rich history of snatching defeat from the jaws of victory. Underestimate Palin to the party's peril. I'd say she's the most significant VP pick in my lifetime given how she's transformed this race. McCain was finished after that DNC convention. Then he plays his hand just right and picks Palin the day after. Pure political brilliance.
