in our current system of voluntary voting, the winner of an election is determined by the candidate’s ability to create controversy rather than by leadership skill. campaigns therefore focus on highly motivated voters. these also tend to be the most partisan. this constant appeal to extremes on both sides of the political spectrum abandons voters in the middle. in turn, these moderates opt out on election day, since none of the candidates seem to be speaking to their concerns. compulsory voting would offer candidates less incentive to inflame passions (ornstein, galston). without having to spend so much of their time trying to appeal solely to the highly partisan voters most likely to show up at the polls, they could instead spend more time crafting policy proposals to meet the needs of all voters. fewer highly partisan lawmakers would mean more cooperation and less unnecessary government gridlock.
