Stunning Figures! Are we moving to a geographical separation?

[Schmitz in 1972]

Our country has always been divided by sociology, but at times it's just been stronger than others. Take the 1850's for example, our nation was so divided in that era that by the time a new decade rolled around we had begun a civil war! And just look at some of the statistics during the elections before and after the war, the south was so solidly democratic (granted of course that blacks weren't allowed to vote except in reconstruction) that no republican could ever win there.  I do believe we are going through one of the most polarized eras in Amercian history but I think we'll come out of it, just as we did the one that lasted the second half of the 19th century
