He first met Carol in the Fifties while he was at the US Naval Academy in Annapolis. He was a privileged, but rebellious scion of one of America’s most distinguished military dynasties – his father and grandfather were both admirals. But setting out to have a good time, the young McCain hung out with a group of young officers who called themselves the ‘Bad Bunch’. His primary interest was women and his conquests ranged from a knife-wielding floozy nicknamed ‘Marie, the Flame of Florida’ to a tobacco heiress.
Carol fell into his fast-living world by accident. She escaped a poor upbringing in Philadelphia to become a successful model, married an Annapolis classmate of McCain’s and had two children – Douglas and Andrew – before renewing what one acquaintance calls ‘an old flirtation’ with McCain. It seems clear she was bowled over by McCain’s attention at a time when he was becoming bored with his playboy lifestyle.‘He was 28 and ready to settle down and he loved Carol’s children,’ recalled another Annapolis graduate, Robert Timberg, who wrote The Nightingale’s Song, a bestselling biography of McCain and four other graduates of the academy.
The couple married and McCain adopted Carol’s sons. Their daughter, Sidney, was born a year later, but domesticity was clearly beginning to bore McCain – the couple were regarded as ‘fixtures on the party circuit’ before McCain requested combat duty in Vietnam at the end of 1966...
Ted Sampley, who fought with US Special Forces in Vietnam and is now a leading campaigner for veterans’ rights, said: ‘I have been following John McCain’s career for nearly 20 years. I know him personally. There is something wrong with this guy and let me tell you what it is – deceit.
‘When he came home and saw that Carol was not the beauty he left behind, he started running around on her almost right away. Everybody around him knew it.
‘Eventually he met Cindy and she was young and beautiful and very wealthy. At that point McCain just dumped Carol for something he thought was better.
‘This is a guy who makes such a big deal about his character. He has no character. He is a fake. If there was any character in that first marriage, it all belonged to Carol.’ carol mccain:
