The results show a region cleaving apart along new electoral fault lines. In the region’s center, clustered along the Mississippi River — where Bill Clinton polled most strongly — the GOP remains largely unchallenged and the voting divide between blacks and whites is deepening. Nearly nine of 10 of white voters in Mississippi, for instance, went for Republican nominee Mitt Romney this year, according to exit polls. About 96 percent of black voters in the state supported Obama.
The pattern is markedly different in the five states that hug the Atlantic coast from Virginia to Florida, which together hold 82 of the South’s 160 electoral votes. A combination of a growing black population, urban expansion, oceanfront development and in-migration from other regions has opened up increasing opportunities for Democrats in those states.
“Georgia is an achievable target for Democrats in 2016,” said Atlanta Mayor Kasim Reed, a frequent Obama surrogate during the campaign. “What you’re going to see is the Democratic Party making a drive through the geography from Virginia to Florida.”
Obama outperformed every Democrat since Carter in the Southeast, except in Georgia, where Clinton did only slightly better in ’96.
