In the tradition of victim-become-commentator, we are witness to a new genre: Betrayed-Wives-as-Spinsisters. MSNBC just sponsored Mrs. Jim McGreevey, wife of former New Jersey governor who had an adulterous affair leading to his announcement that he is A Gay American. The experienced aggrieved wife’s job is evaluate the pain of the new member of this once-private club. The commentator’s countenance must reflect not only sympathy, but ancient wisdom — the sort handed down from the village widows to their virgin daughters. When all else is lost, my child, there’s always a future in TV.
