@Cyan:
The people who are convinced that Joe has dementia (he doesn't and if you know what dementia actually looks like it's really fucked up that people are accusing him of it) are also convinced that Trump is a great witty master of words, jesus goddamn christ.
I'm not a doctor, but three people in my family have had dementia and I can say that every case presents a little differently and largely depends on the individual's personality.
However… I'm not really sure what's wrong with Joe Biden.
There's definitely something abnormal happening to his mind; if you compare clips of him speaking from a few years ago to now you'll see that he didn't selfdestruct in the middle of a sentence back then.
His temper's also much worse, or he's at least far less capable of restraining himself as we saw in his exchange with Corey Booker.
His campaign staff are clearly aware of the problem because they've sought to minimize his public statements and overall on-camera speaking time ever since.
It could be argued that some of his weirder stories (like the one about little kids feeling up his legs and how much he likes it when they sit on him) are also evidence of that lack of restraint.
That speech also shows that he sometimes has a tendency to forget to complete sentences and repeatedly change subject mid-sentence, which is not typical of dementia in my experience.
That's not just a stutter.
I don't see how we can confidently expect him to lead the country in any meaningful way or even function outside of a retirement home, which leads me to assume that his vice president will be taking the reigns the vast majority of the time.
@Monkey:
If anything Biden will look less doddering and old by being next to Trump on stage.
It probably depends on how long Biden has to speak for.
On a good day he can get out several minutes of valid political commentary and sound like a real leader before things start to deteriorate. Give him a good number of breaks and he can last maybe an hour, as he did during one of the recent debates.
I have no idea if there's any way to predict or influence the factors that decide if he's having a good or bad mental health day, though.
