“Such tests arise inevitably out of democracy—the domination of unreflective and timorous men, moved in vast herds by mob emotions. In private life no man of sense would think of applying them. We do not estimate the integrity and ability of an acquaintance by his flabby willingness to accept our ideas; we estimate him by the honesty and effectiveness with which he maintains his own. All of us, if we are of reflective habit, like and admire men whose fundamental beliefs differ radically from our own. But when a candidate for public office faces the voters he does not face men of sense; he faces a mob of men whose chief distinguishing mark is the fact that they are quite incapable of weighing ideas, or even of comprehending any save the most elemental—men whose whole thinking is done in terms of emotion, and whose dominant emotion is dread of what they cannot understand. So confronted, the candidate must either bark with the pack, or count himself lost. His one aim is to disarm suspicion, to arouse confidence in his orthodoxy, to avoid challenge. If he is a man of convictions, of enthusiasm, of self-respect, it is cruelly hard. But if he is, like Harding, a numskull like the idiots he faces, or, like Cox, a pliant intellectual Jenkins, it is easy.
“The larger the mob, the harder the test. In small areas, before small electorates, a first-rate man occasionally fights his way through, carrying even the mob with him by the force of his personality. But when the field is nationwide, and the fight must be waged chiefly at second and third hand, and the force of personality cannot so readily make itself felt, then all the odds are on the man who is, intrinsically, the most devious and mediocre—the man who can most adeptly disperse the notion that his mind is a virtual vacuum.
“The Presidency tends, year by year, to go to such men. As democracy is perfected, the office represents, more and more closely, the inner soul of the people. We move toward a lofty ideal. On some great and glorious day the plain folks of the land will reach their heart's desire at last, and the White House will be adorned by a downright moron.”
