He was a goof off in high school and at the academy, finished 894 out of 899. destroying 3 airplanes and his record in the navy was such that he saw no opportunity to advance to the admiralty and chose politics instead.
He was nick-named “Crash” for a reason.
His fellow pilots nicknamed him Ace McCain, because over the course of his career he destroyed FIVE of his own planes.
But his worst crime certainly was his betrayal of his fellow POW/MIAs in that Senatorial Committee.
His whole life has been a series of betrayals.
Betrayals mean everything to the people of AZ.
