Replication Data for: Do Voters Pay Attention to Transnational Politics? Party Positions, Transnational Families, and Voter Perceptions

Do voters pay attention to a party’s relationship with the rest of its party family? In this paper, I argue that transnational brands such as the party family label assigned to a party are a valuable tool for parties to use to distinguish themselves and reinforce their brand as a credible champion of core ideological battles. In turn, voters can more accurately position parties on the left-right spectrum when the party embraces the ideological profile of the rest of its party family. I test these arguments using the Comparative Study of Electoral Systems (CSES) and the Comparative Manifestos Project (CMP). Then, in a second step I replicate these findings using the German Longitudinal Election Study to further evaluate the causal link between the ideological alignment of party and party family and the accuracy of a voter’s perception of the party’s positions. The results confirm my expectations and provide support for the argument that transnational brands can influence how domestic political parties are perceived. These findings have important implications for our understandings of voter responsiveness in an increasingly transnational political space and how transnational brands can influence domestic politics.
