IS JOHN MCCAIN TOO OLD?

There is a good article in the New York Times about the issue of John McCain's age. McCain is almost 71 and the question is raised repeatedly on the campaign trail. Is John McCain too old to be President? The older we get as a society, the less important age is to us. Although I have never been a John McCain supporter, I have always respected the Senator. I must admit, however, that as I have watched McCain campaigning, he looks old and sounds and acts old. Could that be one reason (along with his stance on immigration) that he has plummeted in the polls?
