If someone called him a Ricardian professor of economics and someone else was like, "Lol that's not a thing" I'd say that the first person was more right than the second, with the same disclaimers I said in my comment.

Again, I think the whole issue is silly. Kamala is not her father. And I don't see being a Marxist as being a bad thing. Considering how much the term gets slung around in US politics to people it doesn't apply to at all, like Kamala Harris or Obama, I think it's kind of silly to push back against it when it's being used with someone who could credibly be called a Marxist. Especially when the much more clear and relevant line is that her father is irrelevant.
