It's also worth noting that Obama didn't do so horrible in the mountain counties of NC. He won a few and was competitive in others. Cross the state line south of Highlands into the North Georgia mountains and Obama was clobbered. Obama didn't crack 30% in a single county in North Georgia, despite being culturally similar to western North Carolina. You might even say that Obama's unusual strength in a region he should not have been competitive in actually won him North Carolina.
I get Obama winning counties like Buncombe, home of Asheville, but can anyone explain to me how he was competitive in the more rural mountain counties?
2 reasons - It's Appalachia(poverty) and moderate race relations in NC.
There was "moderate" Democratic governor during Civil Rights era. The whites in North Carolina were never as polarized as in other southern states. Blacks obviously vote for democrats still. Combined with the poverty of the region I am guessing that's why the two counties voted for Obama.
