Explaining the end of Spanish exceptionalism and electoral support for Vox

The 2018 regional elections in Andalucía marked the end of Spain’s exceptional status as a country with a party system free from the radical right. The electoral success of the radical right-wing challenger, Vox, who gained 11% of the vote and 12 seats in the regional parliament, brought this exceptionalism to an end. This paper analyses the individual-level determinants that explain the electoral success of Vox and the emergence of the radical right within the Spanish party system. The results indicate that concerns over devolution, likely engendered by the Catalan separatist crisis, predominantly explain voters’ preferences for the right-wing challenger. This is true both amongst the general electorate as well as amongst the former voters of other right-wing parties. Significantly, against popular assumptions and empirical observations explaining the rise of radical right-wing parties across much of Western Europe, the results display no empirical link between immigration and electoral support for Vox.
