Once again on here, this mostly shows the left biased perspective.
Trump, though old, is still able to handle himself well, talking publically for hours at a time. If you prune hours of footage of anyone, especially old people, you will be able to find lapses.
Whilst I agree a younger candidate would be a much better choice, his mental agility is still very strong for his age.
Complete contrast to Biden. And notably he’s still a lot smarter than Kamala. She sets up interviews with prearranged questions, talks for less than 15 minutes usually, and still manages to embarrass herself every time she speaks.
