That's true and most people do not realize this fact. Specifically the popularity of fascism. I think people are aware of the popularity of communism. The really interesting thing to me is how popular fascism was and how many of the elite class admired the approach. Some (including me) would argue that FDR was basically a fascist in many ways. Or at least did many of the same things and used the same tactics.

Regardless, the US has been divided before. The civil war for example. My hope is that war is not the outcome again. I think most of us alive today in the US haven't really experienced what a all out war is like. I see this in the attitudes of people that talk about conflict so flippantly.
