Indiana, Montana, North Dakota: As one would expect these are the states were the Democratic brand made the biggest gains (besides Obamawaii).
Virginia, New Mexico and Nevada : If the trends hold these might be safe blue states by 2012
Ohio and Florida Despite going blue this time these important swing states are obviously trending away.
Minnesota and New Jersey: Unexpectedly these are also somehow trending away
Illinois: Only a small Obama-Bounce here.
Texas: If you account that in 2004 the faux native son Bush was on the ticket it looks like Texas is massively trending away from the Democrats. And that is despite the increase in Hispanic population.
Arkansas: WTF's going on here??
