Given the absurdity of his opponent, I still think he could win if inflation makes a dramatic turn for the better in time for people to notice it. He is a weak candidate though regardless given his age and his poor communication skills. People here have pointed out that he has done some good things in terms of policy, but 90% of the country is never going to notice that stuff. It's all about perception.
Today, at thankgiving a dinner, a relative was saying that Biden was terrible because of inflation and needs to go. He said that Trump was stupid but surrounds himself with really smart people and was great for the economy. I asked him to name a smart person around Trump. He admitted that he didn't know and just made that assumption based on how good the economy was. That's just an example of how perception is everything.
