Above is a county-by-county map of North Carolina, shaded to represent where President Obama experienced his largest net percentage margin gain & losses against his Republican contender from 2008 to 2012. The red counties are the counties where Obama did worse against Romney than he did against McCain. Likewise, the blue counties are the counties where Obama performed STRONGER against Romney than he did against McCain. The lighter the shade of red or blue, the slighter the difference in the net margins between Obama & his opponent from '08 to '12. The darker shades of red or blue represent where Obama/GOP saw their largest gains from 2008 to 2012.
Out of North Carolina's 100 counties, only in 19 did Obama perform better against Mitt Romney then he did against John McCain in 2008. Also, African Americans exceeded 30% of the population in all 19 of those counties (whereas they account for 22% of the population statewide).
