examining racial electorate of each state

Pretty interesting statistics. Although I'd like to see Florida and Illinois, and see the data.

Looks like GA and TX vote the same way in terms of racial politics.

here's Illinois:

Separating the white precincts in Chicagoland from Downstate would probably also be revealing.

Like IL it would be interesting to compare the white precincts in suburban Philly with the ones in the rest of state. In IL the Chicago area white precincts were more Obama than average, and I suspect the same is true in Philly.

Don't states with VRA districts actually keep tabs on this?

Not generally. I know that IL doesn't break it down into numbers of precincts.
