I disagree. She has backed away from many of the issues she ran on, voter for the largest transfer of wealth to the 1% in a generation. Look at her FEC report, it is littered with donations from Act Blue, a political action committee.
Why do people keep on suggesting she take some other office? Seriously, does no one want a longstanding force in the HoR? Why don't people want to entertain a hypothetical future of "Speaker AOC" in lieu of "Sen. AOC" or "POTUS AOC"? It'd be just as valuable.
