Why is "age" of itself in-bounds?
Being President is not like being a running-back. The manifold physical aspects of aging are far less relevant than the possible mental decline some elderly people experience. Why is the candidate's age a consideration at all if a particular--I would say the single most important--potential infirmity of aging for the job, the deterioration of mental acuity, is out of bounds. In the last few years we have seen that the public has routinely been shielded from information about various politicians' health -- Jack Kennedy, for example. I think we are absolutely entitled to consider this. It is not an outrage. I see a very different John McCain than 4 years ago. Some may conclude, if they see this, that it's just a calculated political move or a change of heart. I think it is very reasonable to suspect that instead a sort of narrowmindedness is taking hold. On this, I guess we're not going to agree.
