How do voters perceive ideological congruence? The effects of winning and losing under different electoral rules

Abstract

The degree of ideological congruence between citizens and their elected representatives is an important feature of democratic systems of government. A long tradition of literature has examined the ideological linkages between citizens and governments, often drawing attention to the differences (or lack thereof) in congruence across different types of electoral systems. Previous research has largely relied on aggregate-level measures of ideological congruence, such as the ideological distance between the position of the median voter and the government. We turn our attention here to how congruence relationships are perceived by individual voters, and how the perceptions of congruence may vary across electoral system types. This individual-level measure of ideological congruence is important in that individual-level, rather than aggregate-level, congruence has been shown to influence other outcomes such as citizen satisfaction with democratic performance. We expect electoral “winners” – those who voted for a party that entered government – to perceive greater ideological congruence between themselves and the government compared to electoral “losers”. We expect this effect to be stronger in majoritarian systems where political competition takes place primarily between two parties, than in proportional systems where electoral losers are more likely to receive a proportional share of representation. We test these expectations by estimating random-effects regressions of perceived individual-level congruence using data from 54 elections held in 23 democracies included in the Comparative Study of Electoral Systems (CSES). The results provide consistent support for our expectations. Electoral winners in all types of electoral systems perceive greater ideological congruence between themselves and the government, and this effect is stronger in majoritarian systems.
