Electoral Participation in Pursuit of Policy Representation: Ideological Congruence and Voter Turnout

Abstract

In this article, we examine whether lack of ideological congruence with the viable party options discourages turnout, and under which conditions. We conceive congruence from the perspective of the individual citizen, and, drawing on policy-based arguments for non-voting, we hypothesize that: having no party in the political menu sharing similar views should especially reduce turnout of citizens holding extremist views and that this effect would be greatest in proportional electoral systems. Relying on data collected by the Comparative Study of Electoral Systems (CSES), we show that lack of congruence with the electoral menu reduces extremists’ turnout and does so particularly in PR systems.
