Populism and Securitization: The Corrosion of Elite Security Authority in a US–Mexico Border State

Abstract

Abstract Populists have often seemed influential in the securitization of migration, in great part through pressuring non-populist governing elites into “mainstreaming” more hardline immigration positions. This article asks why, given the presumption in securitization literatures that elite insiders possess strong authority in defining security, non-populist governing elites often in fact cede ground to populist challengers who paint immigration as a threat. Securitization and political science literatures paint very different pictures of elite–challenger dynamics, but populist and securitization claims possess key ideational similarities, in relation to the holism and autonomy of the political community, and the apoliticism of pursuing purportedly self-evident goals. However, populism articulates securitarian concepts through a moralized anti-elitism that impugns elite authority, portraying governing elites as corruptly inert toward threats facing “the people.” This article explores how this ideational relationship may affect securitization processes through a process-tracing study of the populist radical right's successful pressuring of governing elites to securitize migration in the US state of Arizona. There, populists’ moralized accusations of corrupt elite inaction toward urgent security threats moved governing elites to adopt positions intended to demonstrate responsiveness to public border-security anxieties, thereby inscribing securitization. Taking an “ideational” view of both concepts shows how they can form a politically influential account of “common sense.” By undermining elite security authority—thus inverting the typically theorized power dynamics of securitization—populism may open new pathways for securitized policies to emerge.
