Changes in voting behavior and the party system in the three federal elections since 1980 indicate that West German politics have entered a new transitional phase. The periods of CDU hegemony, 1949–1969, and two party competition, 1972–1980, have passed. Both major parties have lost support, turnout has declined, ticket-splitting has increased and New Politics issues such as the environment, disarmament and civil liberties have become salient to increasing numbers of voters. The influence of social class, religion and regional ties on voting behavior has declined. Electoral behavior has become more volatile and uncertain. Four major sources of these changes are identified: the postwar transformation of German social structure; the changing value priorities of mass publics; the introduction of new issues; and the electoral strategies of the parties as determined by their elites and leaders. The study concludes with a discussion of the future of the party system and the prospects for a major dealignment or realignment in West German politics.
