More than fifty years have passed since the American Political Science Association published "Toward a More Responsible Two-Party System, " a controversial report that addressed the lack of national cohesion within the major parties. Although parties have changed a great deal since then, they remain a critical component of American democracy.While the possibilities and limits of responsible party government have been central topics in the literature since 1950, this book is the first to reassess all aspects of the APSA report. Here a distinguished group of scholars -- among them Charles O. Jones, Barbara Sinclair, Frank J. Sorauf, John Bibby, and Gerald Pomper -- examines the effectiveness, accountability, and relevance of parties to the democratic process.These articles cover all major relevant topics, focusing on recent changes in laws that govern parties, innovations in party organization, party finance, and the relationships among political consultants and parties. They examine the place of the party in government -- including chapters on the changing role of parties in Congress and in the presidency -- and also consider the roles of parties among the electorate, examining trends in voting behavior, party identification, and ideology. A capstone essay by Leon Epstein, the dean of American party scholars, reviews the ongoing quest for responsible partisanship over the past half century.These contributors offer a mixed assessment of the two-party system, showing that parties are in many respects stronger at the national level than they were in 1950 but not necessarily more responsible. The most comprehensive description and analysis of American parties now available, Responsible Partisanship? should become required reading for all students and citizens concerned with making parties more accountable instruments of government.
