Does election fraud erode support for dictators? An original survey experiment from Russia following the 2020 vote on constitutional amendments reveals three key findings. First, regime supporters and opponents differ significantly in their baseline beliefs about election fairness. While regime opponents are already aware of fraud, supporters expect relatively fair elections. Consequently, only regime supporters revise their election beliefs when exposed to fraud information. Second, fraud revelations reduce regime legitimacy beliefs, but only among the regime’s political base. In contrast, regime opponents already perceive the regime as illegitimate at the baseline. Third, the experiment shows minimal, if any, effects on attitudes toward Putin. While fraud revelations cause regime supporters to adjust their views on the regime, their opinions about Putin remain largely unaffected. The findings imply that dictators can maintain popular support among their political base while manipulating elections, posing questions about the potential of fraud to undermine regime stability.
