You have to realize that the extreme right and left are emotionally pretty much the same, and thus they are easily interchangeable, depending on their whim of the moment. There is no doubt that when Hillary got the Democratic nomination a significant number of Bernie backers slid over to Trump. It is the intensity of the cause that attracts these types.

As Hitler used to say, show me a dedicated marxist and I will show you a potentially fine Nazi.

I could see you, John, easily sliding over to the Democrat camp.
