Slide from my government class where Bernie Sanders is more left wing than China, Pinochet is extreme right wing authoritarian and Milton Friedman is a sweet right wing libertarian despite advising and defending Pinochet. Obama is more authoritarian and right wing than Washington as well.
It's hard to say, but I think that you can make an argument with Mass Line and his tendency for Campaigns where he just kind of nebulously encouraged people to do this and that. I don't think they are talking about re-education during the Cultural Revolution or anything like that.
