Come on, you've got an (alleged) 13-year affair with a woman who, by her own admission, is as broke as the Ten Commandments, and with your wealth you're not MackDaddy enough to at least keep her quiet if not ecstatically happy?
If Ginger White is telling the truth, Cain actually is giving real MackDaddies the world over a bad name, and here's why: when you have a main squeeze for that long (as opposed to playing 'hit it and quit it" with a woman for a few months), she becomes akin to a crime partner and you're joined at the hip with her forever. She knows where the bodies are buried (probably helped you bury a couple of them) and the details of all your other high crimes and misdemeanors. Under any and all circumstances you've got to keep her happy and quiet.
Any MackDaddy worthy of the title would have been able to accomplish this with ease. This dude couldn't manage a sordid little sex affair (she says it never was about love) and he wanted the American public to entrust him with managing sensitive, delicate, and potentially explosive world affairs? Please.
The man never was serious, and going out like a sucker proves it. He was just being kept in the race for comic relief; so the other candidates before taking the stage for a debate had a head to rub for luck.
