Sadly, it sounds like you're describing the incumbent (foot in mouth, saying stupid shit, old, senile, bumbling, racist, perv). Biden is 77, Trump 74 so the same arguments about age apply to both.
I'm certain you are familiar with Ronald Reagan's quote:
"I want you to know that also I will not make age an issue of this campaign. I am not going to exploit, for political purposes, my opponent's youth and inexperience."
The Washington Post had a good editorial on it:

Trump from his recent interview with Chris Wallace:
“We'll put out the flames. And we'll put out in some cases just burning embers. We also have burning embers. We have embers and we do have flames. Florida became more flame like, but it's going to be under control,”
