The formal model presented in the chapter underscores that control over ballot access conveys a significant power advantage to autocratic incumbents. This control leaves electoral oppositions with few options. Yet, even with this power asymmetry, the model demonstrates that elections force autocrats to make strategic choices that reveal information about regime strengths and weaknesses. Banning strong opponents signals regime weakness. Committing fraud to secure victories signals that elections are not mechanisms of accountability. When opposition parties amplify this information, they can generate focal points to foster societal coordination, forcing the regime to respond with concessions or retribution. Depending on the size and structure of the mobilization, these changes can be sudden or incremental, generating uncertainty that has to be addressed in the inter-election period. Through this process, tightly controlled elections contested by weakly organized opposition parties can prompt regime shifts in a liberalizing or autocratic direction. The first part of the chapter presents the model discursively, and the second part formalizes the argument.
