Well, in response to [MENTION=1669]pics[/MENTION] insightful comments, I would say age shouldn't preclude anyone from doing something they really want to do. It's true that modern medicine is allowing older and older people to stay active and involved, often putting younger people to shame. And perhaps an argument can be made that with the interconnectedness of social media and access to knowledge that young people are nowhere near as inexperienced or without knowledge as kids probably were in the past, some of them making coherent arguments and amazing insights putting adults to shame. So, anyone who says there should be a strict age limit on politics should probably think twice.
But that wasn't really the question. It was: does age matter in candidates seeking election? And the answer is clearly yes. But that's only because, unfortunately, we've seen all sorts of a candidate's makeup brought out by competitors for political positions. If they boldly use race, sex, sexual preference, mental illness, and social/economic class to push their candidacy, then of course age is a potential aspect for muckrakers to use, either subtly or overtly.
