Although the CDU and CSU lost support in the 2009 federal elections, their "desired partner" the FDP experienced the best election cycle in its history, thereby enabling a CDU/CSU–FDP coalition. This marked the first change of coalition partner by a Chancellor in German history and the first centre-right coalition government since 1998. CDU candidate Christian Wulff won the 2010 presidential election in the third ballot, while opposition candidate Joachim Gauck (a Protestant pastor and former anti-communist activist in East Germany, who was favoured even by some CDU members) received a number of "faithless" votes from the government camp.
