The minority, however, still continue to exert a controlling influence in most matters of public policy directly affecting their interests as a class, although the extension of the suffrage made the exercise of that control a much more difficult matter and left little room for doubt that actual majority rule would ultimately prevail. A large measure of protection was afforded them through the checks which the Constitution imposed upon the power of the majority. There was no certainty, however, that these checks could be permanently maintained. A political party organized in the interest of majority rule, and supported by a strong public sentiment, might find some way of breaking through or evading the constitutional provisions designed to limit its power. Certain features of the Constitution, however, afforded excellent opportunities for offering effective resistance to the progress of democratic legislation. Entrenched behind these constitutional bulwarks, an active, intelligent and wealthy minority might hope to defeat many measures earnestly desired by the majority and even secure the adoption of some policies that would directly benefit themselves. Here we find the cause that has been mainly responsible for the growth of that distinctively American product, the party machine, with its political bosses, its army of paid workers and its funds for promoting or opposing legislation, supplied by various special interests which expect to profit thereby. With the practical operation of this system we are all familiar. We see the results of its work in every phase of our political life--in municipal, state and national affairs. We encounter its malign influence every time an effort is made to secure any adequate regulation of railways, to protect the people against the extortion of the trusts, or to make the great privileged industries of the country bear their just share of taxation. But the chief concern of those in whose interest the party machine is run is to defeat any popular attack on those features of the system which are the real source of the great power which the minority is able to exert. Try, for example, to secure a constitutional amendment providing for the direct election of United States senators, the adoption of the initiative and the referendum, a direct primary scheme, a measure depriving a city council of the power to enrich private corporations by giving away valuable franchises, or any provision intended to give the people an effective control over their so-called public servants, and we find that nothing less than an overwhelming public sentiment and sustained social effort is able to make any headway against the small but powerfully entrenched minority.
