TBH, while I agree that voter blocks are not matched up with race, I do see the white male stats and have to wonder WTF is wrong with you guys. I think, if you really break it down, it's the urban/rural divide, with rurals and exurbs pretty tight, and polarized with urbs and close-in suburbs. A fair amount of old close-in suburbs are more diverse and generally more aware, and so have moved blueward. But I'd have to comb over some numbers and confer with some expertise before I'd swear to that.
