Much of the night was focused on Biden's biography, but the big moment was the nominee's speech. I think Republicans (and some Democrats) have underrated Biden so much and lowered expectations to such a degree that he didn't have to do that well with his speech to come off OK. But he came out and gave a strong speech, delivered, as some have said here, in an almost fireside-chat manner at times. The setting probably played to his strength , and may have come off better than a speech in front of a huge crowd. I think the clips of this speech will play well on TV or social media tomorrow, and that's how a lot of people will encounter it. Biden made the case for why he can bring a divided country together. He wasn't quite a Hubert Humphrey happy warrior -- he took his shots at Trump, too -- but his message was generally positive, which might play well in an environment where everyone is sick and tired of being sick and tired.
