We're ~25 minutes in, and so far I would say this debate is close, but Walz is edging out Vance. He's not as polished, but he's coming across as more genuine, and he's directly answering.
I will say, I'm enjoying this debate more than I thought I would, simply because the moderators seem competent and both debaters are behaving like actual adults, even if Vance is a makeup-wearing Yale-bot.
That's because he's a genuinely nice person.
