I think Trump could have done better, but overall I loved it. This woman pretty much covers it:
"Shut up, Man" and Joe Biden's Other Best Debate Blunders
I'm linking to it the way I did because there are lots of comments there that are a lot of fun.
But yeah, Trump could have done better, but I don't think Biden recovers from this.
BTW, this will probably be the only debate. I don't think Biden dares do another one.
