She wants a blanket gun ban and wants all civilian-owned guns confiscated; I call that pretty far-left. It's really sad that anyone in the modern Democratic Party who isn't a self-professed Marxist is considered a "centrist" or "DINO." This party has really become unhinged since 2016.
I'm afraid that the damage Bernie Sanders inflicted by normalizing Marxism and bringing it into the mainstream is irreversible.
Are you really going to rank her based on this one issue?
Actual lefties and far lefties would take umbrage with this kind of ranking of her. She caught a lot of flack post-2016 for not embracing single payer, for instance. It's never good to go by just one or two issues, but if you were going to do that, their position on single payer is a good place to start.
