Electoral Choice, Ideological Conflict, and Political Participation

Generations of democratic theorists argue that democratic systems should present citizens with clear and distinct electoral choices. Responsible party theorists further argued that political participation increases with greater ideological conflict between competing electoral options. Empirical evidence on this question, however, remains deeply ambiguous. This article introduces new joint estimates of citizen preferences and the campaign platforms chosen by pairs of candidates in U.S. House and Senate races. The results show that increasing levels of ideological conflict reduce voter turnout, and are robust across a wide range of empirical specifications. Furthermore, the findings provide no support for existing accounts that emphasize how ideology or partisanship explains the relationship between ideological conflict and turnout. Instead, I find that increasing levels of candidate divergence reduce turnout primarily among citizens with lower levels of political sophistication. These findings provide the strongest evidence to date for how mass political behavior is conditioned by electoral choice.
