See how much voter groups have shifted in the 2012 exit polls, compared to 2008. Early numbers are preliminary and may change significantly until midday Wednesday, when poll results are finalized.
The 2012 election mostly went as predicted (given Virginia and Florida's voting pattern, I'd invite you to re-think the "Where Does the South Begin" or at least to contextualize the political and cultural implications for the defining the vernacular region of "the South"). I'm sure we've all seen the electoral college map, but this great graphic shows the demographic groups voting patterns that produced that map.
