New England, the Pacific Northwest and Hawaii. Actually, that might be white men... Could have won whites as a whole in NJ, NY, CA and parts of the Midwest.
Correct, he won all 6 New England states, OR, WA and HI. Also Iowa. In New York it was really close and he might have won but I'm not 100% sure. What about Delaware and DC? I haven't seen any exit polls but I would assume he won the white vote in both.
DC is of course a given. DE whites IIRC went barely for Obama in 2008, so if whites swung similar to the state swing, Romney may have won DE whites.
