I thought it was pretty close, actually. Both dodged lots of questions, him probably more than her. His talking over her and refusing to yield at the end of his time was annoying to me. I didn’t find her expressions and so forth to be annoying, but I get that some people did.
In the end, neither did any real harm, which is about par for VP debates. Given that Harris doesn’t need to move the ball, but the Trump campaign needs to change the conversation somehow, I think it was net benefit to Biden - but certainly not a game changer.
