Where the Votes Come From: An Analysis of Electoral Coalitions, 1952–1968

This paper describes how the contributions that different groups make to a party's total strength can be specified by breaking down each contribution into its three components—size, turnout, and loyalty. Through the use of survey data on reported vote rather than party identification, the voting coalitions of the Democrats and Republicans are analyzed. By means of examples of selected groups, the actual magnitude of these contributions and their components are presented for each of the last five presidential elections. Major attention is given to a group-by-group evaluation of the generally accepted view that the Democrats are a coalition of diverse overlapping minorities including the poor, Blacks, union members, Catholics and Jews, Southerners, city dwellers and perhaps the young; and the view that the Republicans have appeal for the corresponding non-minorities. The empirical results show which aspects of these views are valid and which are not. Some implications for the party system as well as the strategic considerations inherent in this approach are also discussed.
