Support for the Party System by the Mass Public

Compared with most political institutions, the American party system has endured for a long time. The parties as organizations and symbols have become so much a part of our thinking about politics that we generally overlook the possibility of their eventual decline. One of the parties indeed has existed nearly as long as the republic itself; it thus antedates all but a few of the modern nations of the Western world. The basic form of the party system—two major, decentralized, ideologically diffuse parties—has remained generally intact throughout its lifespan. The system of parties as a principle of political organization has been extended in some form to every level and branch of government. When the persistence of the party system has been most in jeopardy—as in the period of the Civil War—it has managed always to reestablish itself. On the criteria of duration, constancy of form, degree of penetration of other political institutions and response to stress, the record of the party system has been one of marked success.This is not to say that there has been no variability in this performance. Constraints were present from the very beginning of party life in this country and have continued—with changing levels of severity—over the years. The failure of the parties to become part of the formal constitutional structure reflects a lack of full legitimation which has proved difficult to overcome.
