I would disagree. If you go back to summer of 2019, evaluating how far Joe Biden’s state-of-mind has gone...then project 18 months into the future where a debate with Donald Trump might occur...Joe is mostly unable to handle question (even if you told him the precise question and answer a week ahead of time).
My advice...Trump should hire a comedian to role-play as Joe and set up a 6-minute clip each week for Twitter. I think Saudi TV has a comedian who is perfect as Joe....just hire him.
Tom Shillue does a damn good job.
