The scenario is becoming all too familiar in this country. A politician is accused of infidelity. He denies the charges and faces pressure to leave. Sometimes he does, sometimes he doesn't, but inevitably, he is weakened. With a few notable exceptions (Bill Clinton, Newt Gingrich), he fades away. This phenomenon raises several questions, such as whether powerful men in our society (and so far, they have almost exclusively been men) are somehow inevitably drawn to sin. Or, giving Mr. Cain the benefit of the doubt, has a tabloid media culture prompted a rash of false or exaggerated accusations?
