As a European this is how I read it too. Politics in the US are so driven by “team sport” and grand personalities the actual policy sometimes gets forgotten. “He says what I think” and “I’ve always voted for party X.” are very common arguments and you may occasionally hear about some wedge issue, but really understanding how these people would govern?
AOC has policy goals and fight for them regardless of her title. If she thinks she can there as President she will run, if not she will do something else.
