I taught Political Science for better than a quarter century to post baby boom Americans.
Along about the end of the 70's I started kicking around the division of the country similar to what this map shows. I usually figured four or maybe five countries emerging from the US but what amazed me is that I can't remember one student in all that time expressing any alarm over my thesis nor one who seemed to care.
Might be time.
