I don't think Obama has a chance in South Carolina.   I also think Missouri will be difficult.  Ohio is a toss-up, but I give Obama a slight edge.  Nevada is a toss-up, but I give McCain the edge.

I don't think McCain will win Maine.   I would make Obama the favorite in Iowa too.  Colorado, Virginia and New Mexico should all be very competitive, with McCain a slight favorite.   Florida should be close too, but the older population will probably swing it to McCain.
