The relevance and resilience of the cordon sanitaire in Portugal: the March 2024 legislative elections

On 10 March 2024, Portugal held a snap legislative election. Marked by a considerable increase in turnout, it inaugurated a new era in Portuguese politics, with the increased support for the populist radical right and a right-wing parliamentary majority. However, a cordon sanitaire strategy kept Chega out of the new cabinet. The election gave rise to a minority coalition government and a tripartite parliamentary landscape, with the mainstream right, the populist right, and the left parties forming three competing blocks. This article examines the 2024 election and a possible link between the rise of the radical right and increased voter turnout. We conclude that the fact that more citizens turned out in this election only partially explains Chega's growth.
