Do reluctant voters vote less accurately? The effect of compulsory voting on party-voter congruence in Australia and Belgium

We know compulsory voting is associated with higher levels of electoral turnout. It has been suggested that this leads to a trade-off with the quality of the vote, i.e. the ideological congruence between voters and the party they vote for. In this study, this claim is investigated using data from the 2007, 2010, and 2013 elections in Australia. We also include a comparison with two recent elections in Belgium, another country with compulsory voting. The results show that reluctant voters vote less ideologically congruent, but that this effect is mediated by political knowledge and political interest. However, this does not lead to less ideologically congruent election results at the aggregate level and compulsory voting does not have an impact on electoral results. We speculate that in future studies, it is important to make a distinction between reluctant voters, and those who take a strong hostile stand on the electoral process.
