The transformation of the new deal party system: Social groups, political ideology, and changing partisanship among northern whites, 1972?1988

Abstract

This paper examines the partisanship of a neglected segment of the American electorate—white northerners. Like their southern counterparts, northern whites have moved toward the GOP (Grand Old Party) and away from the Democratic party during the last two decades. In fact, a substantial plurality of northern whites now identify with the Republican party. Moreover, Democratic losses and Republican gains have not been confined to particular categories of social groups but have cut across groups traditionally identified with the parties. However, political ideology is closely related to the changing partisanship of northern whites. Liberals have become more Democratic and conservatives have become substantially more Republican since 1972. Moreover, the relationship between ideology and changing partisanship occurs within most categories of social group membership, suggesting that ideological orientations now override social group ties in the formation of partisanship. The northern white electorate, in sum, is undergoing an ideological transformation that is reshaping the contours of American politics.
