Autocratization Spillover: When Electing an Authoritarian Erodes Election Trust across Borders

The rich literature on election trust predominantly uses domestic determinants as explanatory factors. But given the international nature of the autocratization wave, can an autocratization event across borders erode election trust? This article argues that an authoritarian's electoral success in a neighboring country can shatter democratic norms and demonstrate the viability of authoritarians. This autocratization event abroad can thus reduce citizens' principled support for democracy and its political system. Consequently, citizens across borders are less likely to see democratic elections as the "only game in town" and they have less trust in elections. To test this idea, I study the spillover effects of the 2018 Brazilian presidential election, in which an authoritarian candidate won decisively. Using the AmericasBarometer in Colombia that was launched throughout this election, I find that the election trust of Colombian citizens erodes after Jair Bolsonaro's electoral success. To probe into the mechanism, I uncover that his electoral victory leads Colombian citizens to be less supportive of the domestic political system and reduces their principled support for democracy. The causal mediation analysis demonstrates that these two variables mediate the effect of the authoritarian's electoral success on election trust. These findings on autocratization spillover effects illustrate the importance of external autocratization events in the study of election trust.
