New Hampshire is interesting. A former solid red state, it is following the Vermont pattern of becoming a moderate-to-liberal state as middle-class refugees from southern New England take advantage of lower taxes and lower housing costs to the north. (I've considered the move myself.) I think the GOP can start to write off New Hampshire.
I'm not sure that the GOP can count on Hawaii to fill the resulting void. If Hawaii goes GOP this year, it will simply be a fluke.
