I see a split between the coastal south from Virginia down to Florida developing in the long run with the lower south changing significantly less. The coastal south, naturally is the part voting for the more liberal party while the gulf/interior south keeps on voting for the more conservative one. Note that I don't say democrat or republican in any of this since I see since I see some party... changes in the near future.
You mean that Democrats will become the traditional Marxian socialist party while the GOP becomes the Fabian-style socialist party. 
Dems are moving to a more elite party. Republicans are moving more populist. Give it 30-50 years and the Republicans could become the more liberal party.
