A century and a half after the Southern States seceded from the United States over the election of Northern Republican Abraham Lincoln a stark political difference remains apparent and is based on almost exactly the same geographic and cultural divides. In the 2012 US presidential race polling data shows that once again the North and South will face off against each other. The North will be aided by the Left Coast while the South and many of the Rocky Mountain and Western Plains States will join forces. This is despite massive demographic change in the form of a flood of Third World immigrants into the South (since the US opened up its border in 1965) and millions of Northern retirees settling in the Southern Atlantic States. In fact, the only Southern States (apart from Maryland and Delaware which still have Southern pockets but have been largely swamped with non-Southerners) which have any chance of voting along with the North are Florida and Virginia, two of the States most radically altered culturally and politically by Northern and foreign immigration. In vast areas of those States (and others such as North Carolina, South Carolina, Georgia, Texas, etc) Southern people and culture has been largely replaced. It’s interesting to note though that despite this demographic deluge, the South still remains different.
Nate Silver’s article for The New York Times includes a map with State by State predictions of the 2012 US presidential race based on the latest polling data. The map is included below. Compare it to the 1860 map and notice that despite everything thrown against it since then as a conquered land subject to US demographic and social manipulation, the South remains different.
