I was a Political Science major in College. I thought of it primarily as history without all the pesky dates. It was, and continues to be, the ramifications of history. So, it interests me.
I agree that what ever form of government you are under tends to continue (Is that the second law of matter and energy?) and that most people are pretty convinced that their particular form of governance is superior. How we treat the poorest members of our society is truly the mark of a government.
Thanks for a very insightful comment.
