Both of them are far too old.
You need someone with life experience and the maturity that it brings, but electing men in their 70's for this high an office is ridiculous IMO.
There are a few older people that would be capable of doing it, but for too many, it's too large a physical and mental strain.
Trump isn't fit to be President on so many levels. Physical and mental health, temperament, attention span, empathy level, knowledge, education, patriotism, lack of understanding (about more things than could be fitted on here). I could go on forever.
I'm sure history will show him as being an utter embarrassment to the nation and a lesson for future Americans. So much of the sh**show that will come out in the future that's been covered up will put the Republican party to shame and hopefully be a sharp further lesson to them.
I look forward to seeing Hillary (can't stand her either but at least she's not Trump) cheering on "lock him up"
