I am not surprised but it makes sense considering AOC's own history. She was an organizer for the Bernie 2016 campaign, for starters. But it's just her style of politics as being rooted in social movements in particular.

Stupidpol seems to think AOC sold out because of compromises in Congress. But that isn't really indicative, considering Bernie is actually well-known (within Congress) for that. He's the "amendment king" in the Senate because he's good at getting what he wants added onto other bills, which is why he's able to deflect attacks like: "why did you vote for X?" It's because he got Y added onto the bill. He's much more of a pragmatic political operator and negotiator despite the public persona as being intransigent -- he is when it comes to the larger issues / themes but much more flexible as a lawmaker.
