Abstract
Populism has become one of the most worrying political phenomena, and given its complexity, one of the most controversial and debated today in social sciences. This article deconstructs and compares the discourses of the Spanish parties that are generally classified as populist —the left-leaning Podemos, the right-wing Vox and the Basque and Catalan secessionist parties EH Bildu, Esquerra Republicana de Catalunya and Junts per Catalunya— according to five dimensions of populism: i) antagonism, ii) morality, iii) idealised construction of society, iv) exaltation of popular sovereignty, and v) personalist leadership. This article shows that, despite significant ideological and programmatic differences, all these parties share many discursive features and a similar way of articulating their communications, interpreting social and political dynamics, as well as instrumentalizing crises to build new political identities.
