This is something I wish that more people understood. In almost any other democracy in the world, Bernie Sanders is only slightly left of center. On a global scale, US Democrats are a center-right party and US Republicans are a far-right party. There are no successful left-wing politicians in the United States.

Good point. The idea that Bernie Sanders (?) is seen as ultra left wing is incredible to me. Americans would probably spontaneously combust if they got to read some of the left of centre manifestos from relatively normal European parties.
