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.
I have explained why the South voted democratic from reconstruction thru and until Reagan. It was a reconstruction legacy handed down from generation to generation. No matter who the Democrats ran as a candidate no one in the South, blacks excluded, would ever vote for Republican up to say 1980. The Party of Lincoln was an anathema.
Ironically before the 1920's blacks voted for the Party of Lincoln and not the Democrats.
