There was, therefore, one form of congressional government which did not succeed. It was a very logical mode of party government, that of nominating the chief magistrate by congressional caucus, but it was not an open enough way. The French chamber does not select premiers by shutting up the members of its majority in caucus. Neither does the House of Commons. Their selection is made by long and open trial, in debate and in business management, of the men in whom they discover most tact for leading and most skill for planning, as well as most power for ruling. They do not say, by vote, give us M. Ferry, give us Mr. Gladstone; but Her Majesty knows as well as her subjects know that Mr. Gladstone is the only man whom the Liberal majority will obey; and President Grevy perceives that M. Ferry is the only man whom the Chambers can be made to follow. Each has elected himself by winning the first place in his party. The election has openly progressed for years, and is quite different from the private vote of a caucus about an outsider who is to sit, not in Congress, but in the executive mansion; who is not their man, but the people's. Nor would nominations by state legislatures answer any rational purpose. Of course every State had, or thought she had,--which is much the same thing,--some citizen worthy to become President; and it would have been confusion worse confounded to have had as many candidates as there might be States. So universal a competition between "favorite sons" would have thrown the election into the House of Representatives so regularly as to replace the nominating caucus by an electing caucus. The virtual election of the cabinet, the real executive, or at least the Prime Minister, the real head of the executive, by the Commons in England, furnishes us with a contrast rather than with a parallel to the election of our premier, the head of our executive, by a deliberative, representative body, because of the difference of function and of tenure between our Presidents and English Prime Ministers. William Pitt was elected to rule the House of Commons, John Adams to hold a constitutional balance against the Houses of Congress. The one was the leader of the legislature; the other, so to say, the colleague of the legislature. Besides, the Commons can not only make but also unmake Ministries; whilst conventions can do nothing but bind their parties by nomination, and nothing short of a well-nigh impossible impeachment can unmake a President, except four successions of the seasons. As has been very happily said by a shrewd critic, our system is essentially astronomical. A President's usefulness is measured, not by efficiency, but by calendar months. It is reckoned that if he be good at all he will be good for four years. A Prime Minister must keep himself in favor with the majority, a President need only keep alive.
