Did any subsets of whites swing towards Obama?

Exit polls did show Obama improved amongst whites in Alabama, 12% in 2008 and 15% in 2012 although that is within the margin of error.  I suspect also much of the change was age related to i.e. older whites still held a racial grudge against a black president so amongst whites who died in the past four years, probably very few voted for Obama in 2008.  By contrast amongst younger whites who weren't old enough to vote in 2008, but were in 2012, I doubt Romney got over 80% of those votes.  He won them but it might have been more like a 75-25 split.  Off course it could be just margin of error.  In Vermont also the overall results were almost identical to 2008 and it is I believe the whitest state so I am pretty sure there had to be some groups who swung towards Obama.
