The Zero-sum Game of Governing Together? Effects of Merkel's Grand Coalition on the Results of the 2009 German Federal Election.

Grand coalitions are highly debated in Germany, where large parts of the media and the political world expect negative effects of grand coalitions on parliamentary party systems. This did not happen either with Merkel's grand coalition resulting from the 2005 election or with other grand coalitions in the German Länder. On the contrary, only the SPD suffered heavy losses in 2009. Most experts agree that those losses were caused by the SPD's participation in the grand coalition. Still, it remains largely unclear how Merkel's grand coalition affected the 2009 federal election. To close that gap, this paper thoroughly analyses the effects of Merkel's grand coalition by looking at a crucial but mostly neglected factor in that regard, the evaluation of the grand coalition by voters. It can be shown that the CDU/CSU was mostly unaffected whereas the SPD suffered from being perceived as the less influential party in Merkel's grand coalition. [ABSTRACT FROM PUBLISHER]
