Yes. 35 is archaic and arbitrary and it unnecessarily precludes Americans from choosing a qualified candidate just because they're "too young."
Age limits are arbitrary, but this is still too low of an age.
Most of the time, of course it is, and the people can see that and make that call for themselves.
But I don't believe that an 18-year-old is just by virtue of his age automatically unfit to govern; in some cases, he could be quite able, or at least be a better choice than the alternatives.
18 is a good choice because that is the age of majority and the age at which one is legally an adult - old enough to serve in the military, old enough to marry, old enough to vote, etc. They should be old enough to run for any elected office, too.
Brain doesn't stop developing til 25. Teenagers aren't the brightest bunch lol, still having raging hormones, and you want to hand them nuclear codes. Good luck with that.
Your brain will continue to develop until the day you die. There is no significance to the age 25 whatsoever, that is something the media flat out made up
