I think you have a situation where he's been so shielded from most Dems even on Capitol Hill, that nobody really actually knows what kind of mental state he is in. That's part of what is causing the absolute panic. The regular rank-and-file house members feel like maybe they were lied to about his true condition, and frankly, so do I.
He did rattle off lots of factoids and actually got better as the debate wore on, which is a mitigating factor.
But the fact that the party leaders themselves seem to be in the dark as to if their candidate is actually in decline or not is a problem,
even if he is perfectly fine. It means he's so isolated that when he stumbles, nobody knows what the hell to make of it.
Meanwhile, Donald Trump has signaled support for trying Liz Cheney via a military tribunal for treason on national television.

I feel like I am in that split second between realizing I am about to crash my car, but not being able to do anything about it. I know that whatever happens next, it's going to hurt.
Personally, I'd rather have a well intentioned animated corpse than a power-hungry maniac that will disrupt many of our alliances. Sucks that is the choice, but that is the current choice.
