The main objective of this article is to highlight the importance of the emotional component in explaining the electoral support for a far-right party, such as Vox. To this aim, the components of the vote for this formation are analyzed, paying special attention to those of an emotional nature (presence and intensity of different types of emotions in Vox voters), in the last two general elections -Congress of Deputies-, of April and November 2019. We use a quantitative methodological approach, based on survey datasets produced by the Political Research Group (EIP) of the University of Santiago de Compostela. The main results presented in this work allow us to conclude the existence of a highly emotional profile among Vox voters, that is expressed in a positive sense towards their own leader and their party. This emotional component also manifests towards the leaders and parties that compete with Vox, although in a positive sense towards right and center-right leaders and parties (PP and Ciudadanos) and in a negative sense towards those located on the left or the center-left (UP and PSOE). Moreover, the multivariate analysis shows the relevance of the emotional component in the explanation of the vote for Vox in the electoral processes, expressed through feelings of hope triggered by its leader (Santiago Abascal) and feelings of fear triggered by the PSOE leader (Pedro Sánchez) among Vox voters.
