Looking for an election link?

where can i find a site that compares clinton vs mccain and obama vs mccain state by state, based on each state's latest polls? and since i MIGHT be asking for the moon, how about the electoral votes for each of those states? is there such a site? and if there is, might that be helpful for the superdelegates to consider, as neither democrat looks likely to get the necessary 2025 delegates without any superdelegates?
