How do electoral manipulation and resulting anti-fraud protests influence political trust in non-democratic contexts? I leverage the plausibly exogenous variation in the timing of a series of original surveys fielded on nationally representative samples in Russia to understand the impact of political shocks – particularly allegations of electoral fraud and post-election protests – on the evolution of trust in political institutions and individuals. This study demonstrates that allegations of excessive, blatant electoral fraud decrease trust in the autocrat. However, trust rebounds following attendant post-election protests. Finally, I examine the conditional impacts of fraud and protest on trust, finding that updating occurs primarily among those with weak political affiliation.
