I do think McCain has a big hole to dig out from under though, and there is not much time left. If I were McCain I would go completely negative over the next month and hit Barack with everything we have on him.
I'd bring up the Odinga connection and even let the "t" word slip out (treason). I'd run enough Rev. Wright ads to make sure he appears nightly in every household in every swing state in America. I'd show the Ayers / flag photo at every campaign stop.
The mushy middle would say it turns them off and the MSM would shout their false charges of racism, but it would shake up the race. It may be McCain's only hope at this late stage.
I think it depends, we see things through a Conservative Lense, how these undecided voters see things is another matter altogether.
IMO McCain should really highlight the differences on the War on Terror and Victory in Iraq and Afghanistan, those issues are crucial to the defense of America, and Obama is pretty much helpless against being hit on his weakness there.
Yeah, and they're 40% of the voters, that's why he doesn't do what you want.
