This study employs an original dataset of Russia's titular regions (also known as ethnic homelands) to understand better how Russia's party of power influences the inclinations of individual voters to cast their ballots. The essay argues that the presence of Edinaya Rossiya (ER, or United Russia) depresses voter turnout in subnational races due to its dominance, which affects the polity in numerous ways. Specifically, dominant parties may scare off quality challengers, result in lower "stakes" for an election, and distort the final electoral outcomes, which together discourage individuals from voting. The study's pooled cross-sectional analysis finds support for this argument. The essay concludes with a discussion of the study's implications for Russia's fragmented opposition parties.
