Realignment Theory

🏛️ Politics & Public Administration By CampusDown Wiki Editorial Team Last updated
Realignment theory holds that certain elections or periods produce large and durable shifts in the party loyalties of voter groups. V. O. Key introduced the idea of critical elections in 1955, and Walter Dean Burnham and others argued that realignments occur in cycles. David Mayhew later sharply criticized the theory's empirical basis.

Critical elections and secular realignment

Key (1955) defined critical elections as contests with intense voter involvement in which the structure of party support shifts sharply and the new pattern persists for several elections. In 1959 he added secular realignment, a gradual shift over many elections. Together these concepts became a framework for how party systems move between stability and change.

Cycles and issues

Burnham (1970) argued that American realignments occur roughly once a generation, citing 1860, 1896 and 1932. Sundquist (1983) explained realignments as arising when new issues cut across existing party lines, a view linked to issue evolution and cleavage theory.

Critiques and modern uses

Mayhew (2000) argued that core claims, such as periodicity and criteria for identifying critical elections, are not supported by the data. Nardulli (1995) found traces of realignment in local data while distancing himself from national cycle theories. Abramowitz and Saunders (1998) reported an ideological realignment in the recent American electorate.

FAQ

What is realignment theory in simple terms?
Some elections cause big shifts in which party people support, and the new pattern lasts for a long time.
Why is it criticized?
Criteria for critical elections are vague, and the claim that realignments occur in cycles is not well supported by data.
