But assuming that we don't know the outcome of the election by this time, Nevada, where Obama has expanded his lead and where much of the state has already voted, could be Obama's ace in the hole—possibly offsetting a loss in Pennsylvania if paired with other pickups like Colorado and Virginia. The key area to watch in Nevada is Washoe County (Reno), which John Kerry lost by 4 points in 2004 but where the Obama campaign has registered thousands of new voters. If Obama wins Washoe, that means the state—and probably the country—is his.
