Incumbent-Aligned Terrorism and Voting Behavior: Evidence from Argentina’s 1973 Elections

Abstract

What is the relationship between domestic terrorism and voting behavior? Past research notes the prevalence of domestic terrorist attacks in democratic regimes, but focuses primarily on such violence as a “weapon of the weak.” We extend this literature by focusing on terrorism by incumbent-aligned armed groups and argue these actors use selective violence against political elites to delegitimize the political opposition and provide credible signals of the instability and unrest that is likely to accompany a transfer of power. Using data from two Argentine presidential elections in 1973, we evaluate the relationship between incidents of violence and changes in two measures of voting behavior—vote share and turnout. Consistent with expectations, left-wing political violence between elections reduced right-wing vote share but did not reduce turnout. Additional tests support the mechanism that violence increased voters’ doubts about a potential right-wing government’s ability to govern, and show violence is correlated with future repression.
