Abstract To what extent do party positions influence voters’ attitudes toward the economic and political aspects of globalization? Initially an issue following a left-right dimension of conflict, globalization increasingly divides mainstream from nonmainstream parties. In this study, I argue that parties help citizens form opinions on globalization issues. I then use data on voters’ attitudes and party positions on globalization to test this supply-side theory of globalization attitudes on both economic and political dimensions. Holding demand-side factors such as economic self-interest and predispositions/values constant, I find that party positions strongly affect voters’ views on economic and political globalization, with the effect being similar to that of education. Moreover, I find that the effect of cues from left- and right-populist parties is much more negative than that of mainstream parties, replicating previous elite-level findings on the positioning of these party families. Finally, green party cues show conflicting results for the economic and political dimensions, with green cues affecting voters negatively on economic globalization but positively on political globalization. The findings in this study call for a deeper exploration of the supply-side determinants of globalization attitudes.
