Critical Elections, Congressional Parties and Clusters of Policy Changes

Profound changes in American public policy have occurred only rarely and have been associated with ‘critical’ or ‘realigning’ elections in which ‘more or less profound readjustments occur in the relations of power within the community’. Since the appearance of V. O. Key's seminal articles on critical elections, an increasing number of political scientists have attributed great importance to such elections. Schatt-schneider views the structure of politics brought into being by critical elections as systems of action. Thus, during realignments, not only voting behavior but institutional roles and policy outputs undergo substantial change. Burnham, perhaps the most important analyst of realignment patterns, alleges the existence of an intimate relationship between realigning elections and ‘transformations in large clusters of policy’.
