It was during this same session of 1868-9 that the Senate teased the executive by throwing every possible obstacle in the way of the confirmation of the much more important treaty with Great Britain relative to the Alabama claims, nearly marring for good and all one of the most satisfactory successes of our recent foreign policy;[18] but it is not necessary to dwell at length upon these well-known incidents of our later history, inasmuch as these are only two of innumerable instances which make it safe to say that from whatever point we view the relations of the executive and the legislature, it is evident that the power of the latter has steadily increased at the expense of the prerogatives of the former, and that the degree in which the one of these great branches of government is balanced against the other is a very insignificant degree indeed. For in the exercise of his power of veto, which is of course, beyond all comparison, his most formidable prerogative, the President acts not as the executive but as a third branch of the legislature. As Oliver Ellsworth said, at the first session of the Senate, the President is, as regards the passage of bills, but a part of Congress; and he can be an efficient, imperative member of the legislative system only in quiet times, when parties are pretty evenly balanced, and there are no indomitable majorities to tread obnoxious vetoes under foot. Even this rapid outline sketch of the two pictures, of the theory and of the actual practices of the Constitution, has been sufficient, therefore, to show the most marked points of difference between the two, and to justify that careful study of congressional government, as the real government of the Union, which I am about to undertake. The balances of the Constitution are for the most part only ideal. For all practical purposes the national government is supreme over the state governments, and Congress predominant over its so-called coordinate branches. Whereas Congress at first overshadowed neither President nor federal judiciary, it now on occasion rules both with easy mastery and with a high hand; and whereas each State once guarded its sovereign prerogatives with jealous pride, and able men not a few preferred political advancement under the governments of the great commonwealths to office under the new federal Constitution, seats in state legislatures are now no longer coveted except as possible approaches to seats in Congress; and even governors of States seek election to the national Senate as a promotion, a reward for the humbler services they have rendered their local governments.
