Why are rural voters more likely to support radical right parties? This paper examines the relationship between living in a rural area and supporting the Portuguese radical-right party Chega. Portugal’s radical right is an interesting case study, not only because of its belated but very fast electoral growth but also because Portugal represents an unusual case of economic convergence between urban and rural areas in the last decade, challenging the traditional explanation for rural populism — economic grievances. Using data from an exit poll from the 2022 elections, we start by showing that living in a rural area in Portugal increases the likelihood of voting for Chega. Then, using a 2023 face-to-face national survey, we use parallel mediation models to test different mechanisms that relate rurality with the vote for the radical right. We find no evidence that cultural and economic mechanisms play a relevant role in the relationship between rurality and the radical right vote in Portugal. Instead, rural residents are more likely to perceive the areas where they live as politically neglected, and it is this perception that feeds into the radical right vote. Political neglect and marginality emerge as the key mediating factor, shedding light on the dynamics of radical right-wing populism in rural regions.
