In any political election, even by universal suffrage (and still more obviously in the case of a restricted suffrage), the voter is under an absolute moral obligation to consider the interest of the public, not his private advantage, and give his vote, to the best of his judgment, exactly as he would be bound to do if he were the sole voter, and the election depended upon him alone. This being admitted, it is at least a prima facie consequence that the duty of voting, like any other public duty, should be performed under the eye and criticism of the public; every one of whom has not only an interest in its performance, but a good title to consider himself wronged if it is performed otherwise than honestly and carefully. Undoubtedly neither this nor any other maxim of political morality is absolutely inviolable; it may be overruled by still more cogent considerations. But its weight is such that the cases which admit of a departure from it must be of a strikingly exceptional character (1861 [1991: 355]).
