I’d call them very clean; because they’ve been brainwashed so well.

Or just called Trump and Vance garbage instead of even talking about their supporters? There’s pretty much never an upside to talking shit about your opponent’s supporters, since if you win you’re going to still have govern them and you already weren’t on their good side to begin with. Granted, these were people that were never going to like Kamala anyways, but why try to add to the hostility? Although, that never seems to stop Trump and Republicans from doing it, so maybe it’s not such a bad idea for Democrats?
