I'm saying the south loved FDR and still do. FDR never lost a southern state and as much as I love the band Alabama, they sang his praises in "Song of the South", 1980s. Carter ans Clinton, two of the most liberal presidents from the south also.
County by county, our differences are rural vs urban, not north versus south. The north has bigger cities, therefore the Dems are able to hold more states, but when the SHTF, the battles will be raging in the north as as much as the south, there will be no Mason Dixon line. Look at Wisconsin with Scott Walker and then look at Austin. Austin Texas is one of the most liberal cities in the nation.
