A Facebook history buff wanted to know if my grandmother was a Democrat. This was in response to my telling the story about my grandmother disliking Wyatt Earp. I replied that she, and most of the cow-boys in the Arizona-New Mexico corridor at that time were Democrats and that the Earps were Republicans. I ended by saying that it's hard to make too much of this political divide because at a later date the two parties switched places.
Well, this last comment was met with hostile resistance and I got the distinct impression that the writer wanted Earp to be a cast-iron Republican (i.e. Trump supporter) and that the cowboys were Democrats (i.e. radical leftist lying manipulators) and the very idea that they ever switched sides was somewhere beyond blasphemy.
So I asked the Top Secret Writer to help explain to us just how volatile the American political landscape has been in the past couple hundred years.
