Does government crackdown on protests related to national elections affect political attitudes? Political-culture research has long considered citizen support of paramount importance for political regimes to thrive and survive. Yet current literature on repression and dissent mainly focuses on how states use coercion and repressive behavior and why individuals participate in protest, but provides little clear evidence as to what extent repression affects citizen attitudes toward the state, and in particular, political trust and support for the government. Our contribution aims to close this gap in the literature by investigating how incidents of state-led violence against protestors influence citizen attitudes towards the political system. Combining survey data on political attitudes from the World Values Survey with event data on election-related contention events from the Electoral Contention and Violence(ECAV) dataset for more than 100 countries worldwide, we use multi-level models to examine the complex relationship between protest, repression, and political support.
