The 2009 Elections in Schleswig-Holstein: Polarised Electoral Campaign,Exceptional Election Results,and an Unspectacular Process of Government Formation

The elections for the Schleswig-Holstein Landtag were held on 27 September 2009. After conflicts between the governing parties the Christian Democrats (CDU) and the Social Democrats (SPD), Prime Minister Carstensen had ended the ‘grand coalition’ and called for early elections, one year earlier than scheduled. The electoral campaign centred on the divide between the Christian Democrats who favoured a coalition with the Liberals, and the Social Democrats who competed for a majority together with the Greens. The elections resulted in large shifts in party strength. Christian and Social Democrats together lost about 22 percentage points of votes, while most of the smaller parliamentary parties attained their best election results in Schleswig-Holstein state elections ever. CDU and FDP gained a majority of seats and formed a coalition that re-elected Carstensen into office on 27 October. Using concepts from coalition theory, our analysis shows that a Christian–Liberal coalition was indeed the most likely outcome of the government formation process.
