Looking at the twenty states most commonly described as swing states in this election, the following table compares current, actual state polling to "expected" state polling. The "expected" numbers take the 2004 state-level result, and shift it 5.96% in favor of Democrats, given that Kerry lost the national popular vote by 2.46% but Obama leads the national popular vote by 3.5%. The current or "actual" state polling is taken from Pollster.com.

There is a lot to say about this table, but I am struck by Alaska, Florida, Montana, Nevada and Virginia. The reason these five stick out to me is that their changes actually result in the state slipping to the unexpected party. Overall, this a 32 electoral vote gain for Republicans, and a 19 electoral vote gain for Democrats, making for a net gain of 13 "expected" EVs for Republicans.
McCain is over-performing the most in Michigan and Nevada, while Obama is heavily over-performing in Alaska, Indiana, Montana and North Dakota. Otherwise, the states are petty much all where one would expect them to be. What do you see in these numbers?
