The man has a mistress with whom he is in love. From the point of view of his wife this is much worse than Clintonesque prowling, much worse. Actually, recovery from this ailment is unlikely. All of them are suffering. Does this mean that he is A BAD MAN and beyond redemption? I suppose that depends on whether or not you believe in the possibility of redemption or if you believe that one's character is revealed by one's actions and that this is the whole story. I am not a Calvinist so I come down on the side of contrition and redemption. The problem for Sanford is that it may well be that he really is not contrite. His wife will know. Perhaps she already does know.
Will South Carolina forgive him? I have always thought that the state is basically divided into two cultural zones. In the Highlands, the Presbyterian, Baptist and generally evangelical spirit of Appalachia seems to prevail. A lot of those people are not going to forgive him.
In the coastal Low Country a much more laid back atmosphere is very visible. My bet would be that he will be largely forgiven in the Low Country.
In any case, he is finished in national politics. pl
