McCain is a nutcase, as evidenced by his singing “bomb bomb Iran” during his presidential run. Like all nutters, he tries to act normal, but the mask always slips. He has been on every side of every issue during his political career, in an attempt to be part of the centrist majority. Most likely his mind was shattered while in captivity, and sadly all that’s left is a shell.
“The object in life is not to be on the side of the majority, but to escape finding oneself on the side of the insane” Marcus Aurelius
