Election recap--or, what's gone wrong with Arkansas?

Here's a fun toy that shows how almost everywhere in the country--even in parts of the deep south--turned more Democratic in the election. Quite obviously, the Ozark Plateau and some of the southern Appalachians haven't gotten some messages over time. Is it that they're still rabid racists who haven't yet joined the 20th Century, let alone the 21st? Is it that they're still Rebels who haven't yet given up the fight against those damn Yankees? Is it that their backwoods religious dogma clouds their vision of how immensely Republicans have screwed us up?
Who can tell?
