Theory: The recent scholarly literature on core political values has p
aid relatively little attention to how values change over time. Drawin
g on studies in social psychology that find that values are reformulat
ed as individuals take on new identities and roles or process new poli
tical information, I argue that choosing sides during a major national
election campaign provokes shifts in core political values. Furthermo
re, in keeping with Philip Converse's (1964) discussion of dynamic att
itude constraint, value change following electoral mobilization is exp
ected to lead to new positions regarding particular government policie
s. Hypotheses: Backing Bill Clinton in 1992 led citizens to become mor
e committed to egalitarianism and less attached to moral traditionalis
m; the reverse is hypothesized to have occurred for supporters of Geor
ge Bush. In turn, changes in levels of egalitarianism caused shifts in
support for federal social welfare spending; new positions on moral t
raditionalism led to changes regarding abortion policy. Methods: Maxim
um likelihood (LISREL) measurement and structural models are estimated
using a CPS panel survey of the mass public in 1990 and 1992. Results
: As hypothesized, presidential preferences in 1992 led to changes in
core value stands, even when measurement error and reciprocity between
value positions and candidate choice were factored in. As the respond
ents' values changed, moreover, their positions on several concrete po
licy items were also significantly modified.
