Sort of interesting that former slave states are now right to work states and former Union states are now mostly union states.
The transformation of the South is remarkable. What was once a solidly Democrat region has done a 180% turnabout, fully embracing Conservatism. As you said, the states of the Confederacy where slavery once existed now are where worker and employee freedom now reign with common-sense Right to Work laws.
And since I'm about to turn 70, I've seen these dramatic changes all within my lifetime.
