It's a very progressive district, that's how she got elected in the first place. This is not a surprise.
I bet my politics fit closer to the other guy, but I'd still vote for AOC between the two because she has a national influence and disproportionate power in the Caucus. If you're actually voting to influence Congress towards helping your district in particular, AOC might get that done even if it's secondary to her national political project. Some moderate guy in a safe D seat would absolutely never get anything for your district.
Would she? I’m not that informed on her politics but I think Bernie supported her, and Bernie is definitely a progressive even by rest-of-the-world standards.
