Kinda thinking that Sarah Palin and the Gustav unconvention are going to put McCain ahead in the polls. Permanently? I have no idea. But for awhile at least, yes. There are indicators that the former is helping, and it's worth remembering how weird the VP slot is--Cheney aside, unless McCain dies she'd be perfect.
And as far as the VP being a "corrective" to the ticket--Biden's experience, Palin's social conservatism, etc.--the angle that's not being explored is that Palin sends a message that JOHN MCCAIN IS GOING TO LIVE FOREVER.
