......Yogi's right. It's never over 'til it's over.
But McCain is attempting to do what no presidential candidate in a similar position has managed to pull off (forget Truman, the polls were way off).
If he does pull it off, it would be truly uncharted territory.
But that's the beauty of politics. Sometimes anything does happen.
At a minimum, don't be surprised if the race closes. It would be a bigger upset if Obama won by 10 points than if McCain won by one
