This is before any active campaigning from Obama.
I'd like to be more optimistic, because these polls won't include new voter registrations, which should be giving the Dems some extra tail wind.
Also, I think McCain is more likely to implode than Obama is. He's such a pile of useless flesh that it's only going to take one slip to kill his campaign.
The chances of him getting to the end of the campaign without saying something cravenly stupid or spectacularly dishonest are not good.
