what would a county map of the us look like

[nclib]

For North Carolina, Obama's best white (or non-black) numbers, (assuming 96% black for Obama) are:

Orange (Chapel Hill)
Durham (Durham)
Buncombe (Asheville)
Jackson (in mountains, contains West Carolina U.)
Watauga (Boone)

Those are the only ones in NC to likely be 50% for Obama.

These would be Obama's worst:

Greene
Bertie
Martin
Jones
Tyrrell

All are in eastern NC and all are quite rural except Greene, which I've heard has a prison.

My calculations placed it about 47-49, so perhaps.

I think this map overstates white Republican strength in urban areas (Philly, Baltimore, St. Louis, Cuyahoga County, Wayne County, MI, etc.) since there is probably lower minority turnout in urban areas. One would expect urban whites to be considerably more Democratic (or at the very least, equally Democratic) than the state average given by the exit poll.
