Joe in his 70s was not really capable of being a firebrand and I think we all knew that. We wanted the trains to run on time and on the whole they did.
Joe's biggest mistake is one that I extend a LOT of sympathy to him for. He needed to groom a successor and he didn't. Nobody who is President of the United States decides 4 years was plenty and it is time to move on. We couldn't have expected him to do that and none of us would have done it ourselves. It could have been Kamala or it could've been someone else, but June was too late. People who say she was not qualified are wrong. She had as good a resume as about any President. But she felt tacked on because she was tacked on. We didn't know anything about what she did for 3.5 years and then suddenly he tells the nation that he needs to step aside (he wasn't the first or second or third or fourth to say it) and he has every confidence in her. I hadn't heard her speak since the VP debate. He could have given her high profile things to succeed at all throughout his term and even if he thought he was doing 2 terms, he could have been setting her up to helm his "3rd Term".
He didn't, though. At least by the midterms, Joe knew 1) He was getting too old for this. 2) Trump was not giving up and would be the nominee unless legal troubles sidelined him and 3) Trump was going to make a good showing at the polls. *I* didn't think Trump would win or make it a really close one, but when your career depends on regular elections, you know it is always a risk.
