You could be right. I was thinking a rope a dope is a real possibility. If there is a debate MSM will rigg it in ways we can only begin to imagine. He held his own with the Bernie one on one. It is being set up so if Joe doesn’t screw up big it will be considered a win for him. Trump should not overly rely on Joe losing solely on the basis that his mind is gone.
On the other hand Joe may have gotten worse. He really does tend to get incoherent when going beyond one sentence answers.
The key is to force Joe off script. They need to allow debaters to question each other.
