There is one respect in which the Spitzer case is unlike that of Mark Sanford: Spitzer had always projected a holier-than-thou self-righteousness in his extortion of assorted businesses and businessmen in the name of “fairness” and full disclosure, and all the while he was consorting with the seediest of callgirls.
Mark Sanford never pretended to be the Second Coming, and had an affair based on at least his definition of “love,” illicit though it was.
Too fine a distinction for me - Sanford should go.
