Party systems and realignments in the United States, 1868-2004

According to David Mayhew (2002: 58-59, 35), "Neither statistics nor stories bear out the canonical realignments calendar of 1860, 1896, and 1932," and "no certifiable electoral realignment has occurred since 1932." This study examines the national division of the U.S. presidential vote and House of Representatives seats from 1868 to 2004 to determine whether realignments occurred in 1896, 1932, and 1968 and whether other elections might be better designated as realignments. The analysis demonstrates the onset of realignments in the 1894-96 and 1930-32 elections and a staggered realignment in recent decades. Republicans registered significant durable gains in presidential voting starting in 1968 and in congressional elections in 1994. The analysis also finds evidence of a realignment favoring the Democrats in 1874-76.
