Is John McCain Sane?

I read this Newsweek article about John McCain yesterday, because I realize I don't know that much about him. Maybe I don't need to, because I am not voting for him, but there is always the possibility that he will win in November. (Please, please, please NO!) I don't know that I learned a lot, but it reminded me of something that has been bothering me for some time, John McCain's sanity.

I do not want to come across as rude, insensitve, or hateful (which I can be at times), but I just don't know a very tactful, compassionate way to ask a question that I have not seen answered.

Did McCain get psychiatric and/or psychological help after he was held as a POW for 6 years? And, if not, exactly how sane is he?

Maybe the information is out there and I have just haven't found it. Maybe people believe that it is none of my business, but I would have to argue about that. He is running to be President of my country, and if Presidential candidates are required to release their tax returns, I think McCain should be required to release his medical records.

While the fact that he is 72 and has had health problems is a concern for me, it is more of a concern that he was a POW for 6 years. While there are many people who could survive a war experience without necessarily coming home with PTSD, how could a person survive 6 years in captivity without some mental stress? Is that possible? I am definitely not a shrink or a doctor, but I am a concerned citizen and this concerns me. Just as the fact that no one else is asking this question concerns me. John McCain is (and should be) very proud of his military service and the fact that he survived those 6 hellish years. This is mentioned on numerous occassions, in varying articles, but (again, as far as I know) he has never spoken on the transition from soldier to POW back to soldier and then to civilian life. And I think the American people need to know.

Am I the only one asking this question?
