The United States has experienced a sharp increase in school and mass shootings in recent years. Previous research has primarily focused on the effects of these events on support for gun regulation and electoral outcomes. This paper focuses on a heretofore understudied consequence of school shootings: counter-mobilization by the pro-gun political right. I provide causal estimates of the impact of school shootings on non-electoral political participation on the right in affected counties by examining donations to the NRA Political Victory Fund (NRA-PVF). Using a staggered difference-in-differences setup, my event study indicates that school shootings lead to an approximately 30% increase in donations compared to the pre-treatment baseline, with elevated levels persisting for several years.
