Split Ticket Voting in Mixed Member Proportional Systems: The Hypothetical Case of The Netherlands

Acta Politica, 2006: 41, issue 2, pp. 163-179

In Mixed Member Proportional systems, voters are able to split their vote. To what extent do voters use this opportunity, which voters seem to use this opportunity most and what are the potential consequences of split ticket voting? These questions are answered by comparatively analyzing motives for split ticket voting and factors that facilitate such behavior and apply them to the Dutch situation. Moreover, we employ various simulations based on the last three parliamentary elections in order to assess the potential consequences of split ticket voting under different electoral system proposals. In general, these results indicate that split ticket voting will not have substantial effects on the distribution of seats in parliament.
