What does what McCain did to Carol McCain mean to you?

He married former model Carol and adopted her children before he was a POW. She waited for him faithfully for years, but had a horrible car accident which left her disabled. When McCain returned he cheated on her with women including beautiful heiress Cindy. He wanted to marry Cindy, so he divorced Carol and married Cindy one month later. Are these the kind of values we want in a President or, does his personal life have nothing to do with his professional one?
