In the last two decades, populist radical right (PRR) parties have been electorally very successful in Western Europe. Various scholars have argued that these parties share an ideological core that consists of a specific form of nationalism (nativism), in combination with two other attitudes (authoritarianism and populism). The aim of this research note is to assess whether this ideological core also exists as a consistent attitude among citizens. Exploratory and confirmatory factor analyses of the attitudes of Dutch citizens indicate that we can indeed speak of a consistent PRR attitude among the public. I also show that this attitude is strongly related to the probability of voting for the PRR Freedom Party (Partij voor de Vrijheid) of Geert Wilders.
