The Republicans now draw most of their strength from the former "slave states." Here's the evidence and the map:
In 2012, Republicans won only 55 electoral votes from the free states. Obama carried 332.
I don't think it's coincidence or merely an association. I think it's a cause.
In order to support slavery, a person has to deform and distort his brain; he has to learn to make or accept arguments that are innocent of fact and logic and fellow-feeling. He has to damage his intelligence and ruin his morals, and, apparently, he must pass the consequences on to his children and grand-children.
And so the sins of slavery continue to be visited upon us, yea even unto the seventh generation.
