final argument against Obama

Do you think that Obama is going to win because the Republicans have such a bad candidate?
Why did John McCain make his final argument against Obama... coal?
That's his closing argument? William Ayers, Rev. Wright, spreading the wealth, Born Alive, meeting dictators without preconditions, etc. all have to take a back seat so that McCain can go to Colorado and New Mexico to talk about coal? Does this more or less explain why he's going to get his clock cleaned Tuesday?
