Powerline sums up McCain beautifully:

McCain himself seems to me beautifully captured in the almost Churchillian quote from JFK's inaugural with which we conclude our column. JFK described himself as the representative of a generation "tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage--and unwilling to witness or permit the slow undoing of those human rights to which this Nation has always been committed, and to which we are committed today at home and around the world."
