I am curious as to why some on the forum feel the South will become more Democratic over time. Its possible for sure but I am curious why (save for the "affluent whites moving in" theory which may be highly valid).
Does anyone see any possibility that any signifcant urban area will turn Republican?
Depends on where you are talking about. Some areas will fit in the well educated affluent northern whites moving in. Others such as Mississippi have to do with the demographics and ages of the white and black population. Blacks skew much younger in Mississippi than whites do, the over 65 population in Mississippi is predominately white. So as the elderly die off the dynamics of the voting population change, and the black % of the voting population increases.
Now it won't probably be enough to make the state Democratic or even toss up, but it can certainly push it away from solid status.
