How do voters react when their party forms a coalition they dislike?

While coalitions are conventionally seen as opportunities for parties to realise their policy preferences or to secure their control over political offices, recent studies show that citizens have preferences for coalitions which influence their vote choice. However, these studies do not consider how party and coalition preferences influence each other. This study uses panel data from the German Longitudinal Election Study from the 2009, 2013 and 2017 German elections to determine whether voters punish the party for which they voted for being in a coalition they dislike or, alternatively, whether they become more supportive of that coalition. We find weak evidence for the former but strong evidence for the latter.
