stop we can't pretend that a 77 year old will necessarily have the same stamina, energy and even - let's face it - mental capacity to sustain a successful and safe presidency for four full years, as, say, a 50 year old would likely have. I know that when my Gran was 77 she had the beginnings of dementia, but it only became clear when we looked back over the years what had been going on.
It's not ageism to recognise that most people are knackered by 77 and most often are fully retired, for sensible reasons.
Vote if you agree with his policies? Sure.
Also have concerns about his age? Perfectly understandable.
