 The format, the mute button, actually seemed to help Trump hold back on some of his instincts to interrupt Biden, especially in comparison to four years ago. I mean, Trump sounded more measured than he did in past debates. Yet it also didn't stop him from spreading a lot of falsehoods and personal attacks. But the mute button kind of prevented Biden from being able to kind of fact check or kind of respond to it. And also the moderators did not do any of that either.
