I'm old enough, as you are, to remember Biden from over a decade ago. He was still flubbing sentences and putting his foot in his mouth then. I've watched him of late in interviews and I think he's fine. Is he old? Yes. Does he seem to have dementia, Alzheimers or even severe cognitive decline? I don't see that. Anyone at his age will not have the same jump in their step that they did at 50 or even 60, but I'm convinced that the presidency is about surrounding yourself with capable people and having the ability to be deliberative. I think Biden will do that and have that. I am still holding out for Yang 2024 though :) But down with Trump. This galvanized my disdain (as if it needed it): https://www.npr.org/sections/live-updates-protests-for-racial-justice/2020/06/28/884392576/trump-retweets-video-of-apparent-supporter-saying-white-power
