They shall not pass? The role of supply-side factors in the electoral breakthrough of VOX and Chega

Abstract

ABSTRACT No country is immune to the electoral success of populist radical right (PRR) parties: Spain and Portugal seemed to be the exception to this rule because, for decades, PRR parties remained relegated to the margins of the Iberian political systems. However, in 2019 VOX and Chega gained parliamentary representation: how did they manage to obtain their historic electoral breakthrough? From a supply-side perspective, we use the Party Manifesto dataset to show that VOX and Chega chose to position themselves within the existing political space and cleavages in ways that set them apart from the competition. VOX exploited the Spanish centre-periphery cleavage insisting on strong nationalist elements while advocating for increased centralization, while Chega insisted on personal freedom and welfare limitation to break the ties with the political system born out of the Carnation Revolution.
