I think you are right. I've also been wondering if there might be a back door attack through Cheney with some 'new' revelation about Halliburton, that evil empire. All they need is a 1-2% swing or a similar reduction in turnout.
On the other hand, what type of revelation about Kerry would dissuade his base from coming out? Let's see - they are pacifists, yet give him a wink about his war hero status. He is filthy rich because of his use of women, yet he gets a pass from the feminists. They are animal rights activists, yet he kills a goose. The worst thing that could be leaked about him to suppress his base would be???
Turnout is key, of course.

Watch for fRance to leak a false document about a french Halliburton subsidiary being on the take with Saddam's oil for food
You've hit the nail on the head. He's invulnerable to attack because even among his supporters, there is a pretty clear recognition that there's no there there. He's been invisible in the Senate for 20 years. They're not buying a leader, certainly not a moral example. He doesn't have to be anything...so long as he's not BUSH! That's the campaign in a nutshell.
