I encountered a video of one Bernie supporter. There was a picture showing that Sanders is actually a centrist, but not a socialist as everyone labelled him.
I don't know if I ever seen clearer representation of what Steven Pinker called political/ideological pole. In that case Left Pole. The terms takes analogy with geographical poles. Basically if you staying at the north pole any direction from you will be south. So, Left Pole means that you are so far left that anybody who has different views from you would automatically be labelled as right-wing.
That image was obviously made by people who strongly lean towards left. For them Sanders and Warren are in the centre or on The Pole. So, every other American politician ends up as right-wing authoritarian. Where Trump is the most hardcore authoritarian , together with Boris #eyeroll #facepalm
Notice that Auth-Left and Lib-Right areas are almost empty. Plus I think people who made this give Trump too much credit. I don't even think it is reasonable to assess his ideological stances at all. Like what's the point? He can barely utter a coherent sentence...
