One word, well 2 sums this up: sad and embarrassing. There were no winners, neither Biden, Trump, nor the especially, the American people. We all lost. The only positive I can see out of this, is that Biden has the lead, and I dont see this debacle changing it. Trumps base will eat his antics up, and the "at least Biden is not Trump" voters will have even more reason to vote that way, even though I thought Biden looked weak on backing up his statements at times, and should have not resorted to so much name calling. And yes, I know, Trump told lie after lie, but that is what we expect of him.
Really, I think the remaing 2 debates should be cancelled unless they can be moderated and fact checked more effectively. At least when one candidate has 2 minutes "uninterrupted", they should cut the microphone of the opponent.
