The effect of socioeconomic policy and competence messages on populist radical right support: Evidence from a pre-election survey experiment

Abstract

Does highlighting socioeconomic policy considerations or mainstream parties' government competence reduce support for populist radical right (PRR) parties? Such "defuse" messages may attract PRR voters without alienating mainstream parties’ core electorate and thus, have advantages over an accommodative strategy. This study tests four "defuse" messages in an original survey experiment on a sample of 1,786 likely PRR voters in the context of the 2017 German federal election. The findings show that potential PRR voters are hardly swayed by these messages. This result is in notable contrast to findings from prior experimental studies about the malleability of PRR support. Exploratory analyses suggest that some of these null findings may mask heterogeneities. Both respondents who were surveyed during the first days of fieldwork and those with less political knowledge responded to some treatments in the expected way. Overall, these findings point to a limited responsiveness of PRR voters to "defuse" messages.
