*He has had some moments of lucidity lately*
I wonder how many “takes” it took until his handlers got a few moments strung together to make him appear lucid. If it wasn’t a live performance you saw, then it was staged and practiced over and over again, and the successful scenes were pieced together neatly. What you saw was just good production and editing.
I agree with that.
Also, you may have seen an ad that Joe was running on YouTube. You can bet that was rehearsed and filmed many times, as you indicate. They got the best possible presentation they could and showed it on YouTube for a few weeks. His opening line went something like this: “This is Joe Biden I want to for this message to you …”
That was the best they could do.
