If the 'honest services' theory—broadly stated, that officeholders and employees owe a duty to act only in the best interests of their constituents and employers—is taken seriously and carried to its logical conclusion, presumably the statute also renders criminal a state legislator’s decision to vote for a bill because he expects it will curry favor with a small minority essential to his reelection; a mayor’s attempt to use the prestige of his office to obtain a restaurant table without a reservation; a public employee’s recommendation of his incompetent friend for a public contract; and any self-dealing by a corporate officer. Indeed, it would seemingly cover a salaried employee’s phoning in sick to go to a ball game.
