You do realize, that parties have shifted, Lincoln would be a Democrat/Progressive today, while conservative "religious" south became republican.
There was no shift.

"Democrats still can't explain why former Senator from West Virginia Byrd was a Grand Wizard of the KKK."
"The Democrats haven't changed one bit since the days of legalized slavery - They are still committed to mass importing a steady flow of cheap workers to do all the donkey work for them; for as little wages as possible. Democrats are by their very nature elitist snobs who believe that any form of manual labor is far beneath them."
