AOC is a "communist"? Does she propose that the US government nationalize all of the centers of economic power in America? The fossil fuel industry, mining, all of the utility companies, the banks, healthcare, the military-industrial complex, big pharma..etc. Is that what she wants? No not at all. Does she assert that every American has an inherent, human right, to food, housing, healthcare, education, and employment in the public sector? These are just the basics of communism.
She's a social democrat at best, and I don't consider her even that. She's just a liberal, not a genuine leftist, much less a Marxist.
