Biden did what he needed to, not seem sick or weak. His answers were ok, but he didn't say anything that I thought had a good punch. But it's hard to notably punch the guy that everyone else spends all day punching.
Trump needed to back off, save the "classic Trump" stuff for later. Came out of the gate way too fast. But he has no crowd, and that's his happy place. It seems like his best line of attack was the Hunter Biden stuff, but he flubbed when Joe brought up his dead kid. Should have praised then pivot, instead he just pivoted.
Not sure what his plan was for the taxes fight. Either just lie it all away, or what he meant to say was "I pay millions in taxes through my business, not personal income, that's just how it works." But he didn't get that across.
His climate answers were good-not-great, but firmly good. Medical was all over, but Republicans have been dropping the ball on Obamacare replacement for years. Better answer: I'm not going to bankrupt the American economy on unproven technology and theories when we can spend the money meaningfully protecting our rivers, forests, and oceans from pollution. He did get Joe to fumble a bit with the green new deal.
The pandemic stuff was weak. He could have slaughtered Joe by pointing out the sheer stupidity of blaming him for the number of deaths, and keep going back to January, but instead he just kept saying how couldn't handle it. Weak.
The hunter biden stuff seems to shake Joe the most, so I bet there will be more of it. You can tell Trump doesn't do well in a dynamic debate. There were some softballs he missed completely because he's so stuck on what he expected to be asked. Two examples were condemning white supremacists and committing to an orderly transition. Those are "Yes, but..." questions, and he turned them into just "but..." questions. He could have scored home runs on both of those.
I don't think the first debate moved the needle.
