Honestly, bud, both choices seem awful, and maybe you need to be outside of America to see it, but dang, neither of these guys would be my choice to lead the most powerful nation in the world through the next four years, based solely on the risk that neither of them will make it through them. Biden is a million years old, and Trump would need to basically be mumified to protect his body against the stress he's putting it through with all his drama...his heart must be a ticking time bomb, with his portly figure. Forget about the cognitive stuff.
That either side would say that either of these guys are the ticket seems to merely demonstrate the extent to which polarization has taken over common sense in the USA. You guys aren't even voting for a president anymore, you're voting for a mascot, not to do a great job of government but to get one over on the other side. It's full self destruct mode. As your nearest neighbor, I'm very nervous about the ripple effect.
Given no other choices, if it were me I'd probably vote based on the Vice President at this point, basically.
