We present evidence of a historic realignment in the relationship between class and
voting behavior in U.S. presidential elections in the postwar period. We take advantage
of recent advances in class analysis and statistical methodology to introduce a distinction
between "traditional" class voting and "total" class voting. Neither shows a decline
in the postwar era. The realignment occurred since 1968, as professionals and nonmanagerial
white-collar workers moved from voting for Republicans to supporting Democratic presidential
candidates. Stronger support for Republicans among the self-employed and among managers
has more than offset the shift of professionals and nonmanagerial white-collar workers
to the Democrats. Skilled blue-collar workers have become volatile, moving away from
their historic support for the Democratic Party without firmly attaching themselves
to the Republican Party.
Significant class differences in voter turnout also contribute to the total association
between class and voting outcomes.
