Race is a huge factor. Not only against, but for. I guarantee more blacks will vote in this election than have ever voted before. Guarantee that. So it's really a moot point, the race issue, as for every white who won't vote for Obama solely based upon race, you'll have a new black voter who has never voted before, counterbalancing. Thusly, to ultimately answer your question, no, race will not really factor into the "final score".
