Because, no matter how stupid or perverse the person elected, the majority was always the stupider and more perverse for having done so. Cynical but true, Shaw's critique of political voting exposes the leveling effect of the process. Since a majority cannot be formed at a higher level of intelligence than that possessed by those elected to office to represent them, many of the participants will have settled for a lower standard of judgment than they normally use in their own everyday lives. Such is the nature of a majority. The result may be heart-warming for egalitarians with an inferiority complex but it does no justice to the prospects for human achievement.
Politicians are fond of citing public opinion as the basis for their authority.
This they claim to know by virtue of their elected position. Actually, scarcely anything could be farther from the truth because the political process of election will have deprived them of any access to such knowledge, whatever it might mean, if anything. While the voters may be equally qualified to respond to the polls and cast ballots, serious questions arise in the process of election. At the outset, all the ballots are alike as befits universal suffrage. When voters go to the polls, they take along all their delusions but leave their sense of humor at home.
