“McCain knows survival and endurance and how the military works but…,”

I wouldn’t poo-poo that experience too fast, running a squadron is no small feat. Even with all the cookie cutter set ups and regulations, it acts organizationally like both a small city or like a large business. Add to that the mental toughness which allowed McCain and his fellow POW’s to survive and I am not sure there is much out there that could take McCain out or put him off balance, He’s survived some of the most partisan politicizing since the Civil War, and came out with his honor and sense of purpose intact.

I do not know of many who can make the same claim.
