And yet a sort of decision emerged; Mr. Harding moved into the White House. For the least common denominator of all the votes was that the Democrats should go and the Republicans come in. That was the only factor remaining after all the contradictions had cancelled each other out. But that factor was enough to alter policy for four years. The precise reasons why change was desired on that November day in 1920 are not recorded, not even in the memories of the individual voters. The reasons are not fixed. They grow and change and melt into other reasons, so that the public opinions Mr. Harding has to deal with are not the opinions that elected him. That there is no inevitable connection between an assortment of opinions and a particular line of action everyone saw in 1916. Elected apparently on the cry that he kept us out of war, Mr. Wilson within five months led the country into war.
The working of the popular will, therefore, has always called for explanation. Those who have been most impressed by its erratic working have found a prophet in M. LeBon, and have welcomed generalizations about what Sir Robert Peel called "that great compound of folly, weakness, prejudice, wrong feeling, right feeling, obstinacy and newspaper paragraphs which is called public opinion." Others have concluded that since out of drift and incoherence, settled aims do appear, there must be a mysterious contrivance at work somewhere over and above the inhabitants of a nation. They invoke a collective soul, a national mind, a spirit of the age which imposes order upon random opinion. An oversoul seems to be needed, for the emotions and ideas in the members of a group do not disclose anything so simple and so crystalline as the formula which those same individuals will accept as a true statement of their Public Opinion.
But the facts can, I think, be explained more convincingly without the help of the oversoul in any of its disguises. After all, the art of inducing all sorts of people who think differently to vote alike is practiced in every political campaign. In 1916, for example, the Republican candidate had to produce Republican votes out of many different kinds of Republicans. Let us look at Mr. Hughes' first speech after accepting the nomination. [Footnote: Delivered at Carnegie Hall, New York City, July 31, 1916.] The context is still clear enough in our minds to obviate much explanation; yet the issues are no longer contentious. The candidate was a man of unusually plain speech, who had been out of politics for several years and was not personally committed on the issues of the recent past. He had, moreover, none of that wizardry which popular leaders like Roosevelt, Wilson, or Lloyd George possess, none of that histrionic gift by which such men impersonate the feelings of their followers. From that aspect of politics he was by temperament and by training remote. But yet he knew by calculation what the politician's technic is. He was one of those people who know just how to do a thing, but who can not quite do it themselves. They are often better teachers than the virtuoso to whom the art is so much second nature that he himself does not know how he does it. The statement that those who can, do; those who cannot, teach, is not nearly so much of a reflection on the teacher as it sounds.
