The Effectiveness of Discursive Frames Deployed by Latin America’s Right-wing Populists: Evidence from Costa Rica

Abstract Over the last 20 years, many countries have experienced the rise of radical right-wing populist (RRP) actors that threaten democratic governance, including in Latin America. These actors have deployed a variety of discursive frames based on economic grievances and (perceived) changing social values. The 2018 elections in Costa Rica were part of this phenomenon: a right-wing populist outsider presidential candidate deployed several frames and earned the most votes in the first round of voting. We analyze support for this candidate to understand which sectors of society were galvanized by the deployment of economic, anti-establishment, and cultural frames. We find that economic frames had much weaker traction than anti-establishment and cultural frames and that opposition to same-sex marriage was the frame with the strongest galvanizing effect across a wide range of demographic groups, beyond the expected ones. These findings support extant scholarship demonstrating the effective politicization of cultural issues by RRP actors for electoral purposes.
