Not sure what you mean. The Bernie Sanders left has been attacking the same people that Trump’s supporters are attacking for years now. The Occupy movement and other groups on the far left are just as vehemently anti-establishment as Trumpists. The difference is in how each side sees the solution to the corruption of the elites.

Trumpists want to replace the liberal meritocracy with Theo-fascist leaders, while the far left wants socialists to take charge. If I had to choose, I’d go with the socialists, but in general I’m in favor of reforming institutions piecemeal rather than burning them down the way Trumpers and the far left want.
