Strategic coalition voting: Evidence from New Zealand

Abstract

Whereas the classic literature on strategic voting has focused on the dilemma faced by voters who prefer a candidate for whom they expect has little chance of winning a seat, we consider the dilemma faced by voters in PR systems who do not expect their preferred party to be in government. We develop hypotheses relating to strategic voting over multi-party governments that we test using the New Zealand Election Study (NZES) campaign study of 2002. We find evidence that expectations play a role in structuring vote choice. While there is clear evidence of wishful thinking there is also evidence that voters respond to expectations about government formation. These expectations may mobilize voters and lead them to defect from their first preference.
