Abstract Which predispositions drive voters’ policy attitudes? This article tests the role of political values as a driver of attitudes relative to two commonly posited sources – partisanship and symbolic ideology. Past work has found correlations between values and issue attitudes, but these cross-sectional studies have limited causal purchases. I test the effects of traditionalist and egalitarian values on issue stances using six ANES and GSS panel surveys from 1992 to 2020. I find that values drive within-voter changes in policy attitudes under a variety of specifications. Additionally, values shape attitudes on emergent policies, which I test using the cases of welfare reform in the 1990s and transgender policies in the 2010s. In all models, values have as large or larger effects on attitudes as that of partisanship or ideology. I conclude that values are a core predisposition which voters employ to make sense of policy issues.
