The final debate four years ago is a great example of this. Trump was still Trump but he at least was able to stay on message for a portion of the debate and it was likely his best performance.

But Trump is way more unhinged today than he was four years ago. He hasn't been on message at any point since his Oval Office address back in March.

So, it would not surprise me if he came out and just totally mucked everything up.

I still don't think he does it. But who knows? It's clear his handlers have no control over him. So, their advice isn't being heeded.
