The only universally valid critique I have of her is that Bernie was much more of a populist in rhetoric, constantly going after billionaires, never really talking about himself, whereas AOC has a tone much more comparable to say Warren.

She and all of the other further left members of congress would cleanly fit into GUE/NGL type parties in Europe which are left of succdem but aren't communist. It's essentially just 1960s succdems.
