You formulated it as though you were bringing up something new: “you mean the same X who Y” is for introducing something new into the conversation in relation to X, with X here being Jill Stein. If you had just used David Duke as X and “who lead the KKK” as Y, it wouldn’t have been an absurd contribution.

Though it would still be a silly one, since people know who David Duke is, it’s not some obscure fact. He’s the single most recognizable name in connection with the KKK, perhaps along with the long-dead D.W. Griffith (but probably not).

Ah, you were a different user jumping in, my bad. Either way, that’s what was asked originally.

My personal opinion? Claudia De La Crúz all the way.

It’s important to note that Duke endorse Stein because she supports ending support for Israel, and Duke hates Jewish people, he doesn’t care about genocide at all.
