This article examines the 2022 Brazilian presidential campaign to explore the dynamic relationship between political alignment and electoral trust. We argue that trust in elections is not solely a function of partisanship but is also influenced by exposure to elite narratives and citizens’ expectations about who will win. Using a five-wave panel survey conducted during the 2022 election in Brazil, we analyze both between-individual differences and within-individual changes in vote intention and trust in Brazil’s electronic voting system. Employing within–between models, we separate stable partisan differences from changes associated with individual-level shifts in political alignment. We show that then-President Jair Bolsonaro’s voters consistently expressed lower trust in the electronic voting system compared to other voters. Yet, among Bolsonaro voters, trust in the electronic voting system was significantly higher for those who expected him to win and lower for those who expected him to lose. Critically, exploiting within-person variation, we show that switching vote preference toward Bolsonaro is associated with declines in trust. These findings suggest that elite cues and outcome expectations interact to shape electoral trust.
