The President does come to the assistance of Congress by delivering messages on the state of the Union. He is in a position to do that because he presides over a vast collection of bureaus and their agents, which report as well as act. But he tells Congress what he chooses to tell it. He cannot be heckled, and the censorship as to what is compatible with the public interest is in his hands. It is a wholly one-sided and tricky relationship, which sometimes reaches such heights of absurdity, that Congress, in order to secure an important document has to thank the enterprise of a Chicago newspaper, or the calculated indiscretion of a subordinate official. So bad is the contact of legislators with necessary facts that they are forced to rely either on private tips or on that legalized atrocity, the Congressional investigation, where Congressmen, starved of their legitimate food for thought, go on a wild and feverish man-hunt, and do not stop at cannibalism.
Except for the little that these investigations yield, the occasional communications from the executive departments, interested and disinterested data collected by private persons, such newspapers, periodicals, and books as Congressmen read, and a new and excellent practice of calling for help from expert bodies like the Interstate Commerce Commission, the Federal Trade Commission, and the Tariff Commission, the creation of Congressional opinion is incestuous. From this it follows either that legislation of a national character is prepared by a few informed insiders, and put through by partisan force; or that the legislation is broken up into a collection of local items, each of which is enacted for a local reason. Tariff schedules, navy yards, army posts, rivers and harbors, post offices and federal buildings, pensions and patronage: these are fed out to concave communities as tangible evidence of the benefits of national life. Being concave, they can see the white marble building which rises out of federal funds to raise local realty values and employ local contractors more readily than they can judge the cumulative cost of the pork barrel. It is fair to say that in a large assembly of men, each of whom has practical knowledge only of his own district, laws dealing with translocal affairs are rejected or accepted by the mass of Congressmen without creative participation of any kind. They participate only in making those laws that can be treated as a bundle of local issues. For a legislature without effective means of information and analysis must oscillate between blind regularity, tempered by occasional insurgency, and logrolling. And it is the logrolling which makes the regularity palatable, because it is by logrolling that a Congressman proves to his more active constituents that he is watching their interests as they conceive them.
