On 3 June 2010, Christian Wulff, the incumbent Premier of Lower Saxony, was nominated as the candidate of the government parties. Prior to this, Federal Minister of LabourUrsula von der Leyen had been considered the front-runner for the nomination of the government parties. Because the Constitution of Germany forbids the President to hold other offices, Christian Wulff resigned from his seat in the Landtag of Lower Saxony on 11 June 2010 and announced to leave the supervisory board of Volkswagen the following week. He resigned from his post as Premier of Lower Saxony upon being elected as President on 30 June, handing his resignation letter to Landtag President Hermann Dinkla, who was also a delegate to the Federal Convention, before heading towards the podium to formally accept his election.
On 3 June 2010, the Social Democratic Party, the Greens and the SSW, nominated independent Joachim Gauck, an anti-communist civil rights activist from East Germany and the first Federal Commissioner for the Stasi Records, as their presidential candidate. In the days following the official nominations, several FDP and CDU politicians expressed their support for Gauck, among them former Brandenburg CDU chairman Jörg Schönbohm and Oliver Möllenstädt, chairman of Bremen's FDP. Gauck is viewed as a liberal conservative, enjoying respect across political parties. Also Bavaria'sFree Voters, who send 10 delegates to the Federal Convention, said they would not nominate a candidate of their own, expressing sympathy for Gauck. Philipp Freiherr von Brandenstein argued that the election of Joachim Gauck would prevent any cooperation between SPD, Greens and the Left Party for years to come: "Gauck has likely made it perfectly clear to Gabriel that he will never appoint any of the apologists of the communist tyranny as government members". While co-chairman of the Left Party Klaus Ernst initially indicated that his party might support Gauck in a possible second or third ballot, Gregor Gysi, chairman of the Left's parliamentary group in the Bundestag and Oskar Lafontaine, former co-chairman of the party, voiced their opposition to voting for Gauck, criticizing his support of the War in Afghanistan and the Hartz welfare reforms. Katja Kipping, a member of parliament for the Left Party, claimed Gauck was a "man of the past". Kipping lauded Gauck's role in investigating Stasi injustice but criticized "equating Hitler-fascism and the GDR", which she perceives as a "trivialisation of fascism". Klaus Ernst subsequently retracted his statements, stating that the Left will not vote for Gauck. Gauck himself warned the SPD and Greens against cooperating with the Left. Sigmar Gabriel, the SPD chairman, described Lafontaine's reaction as "bizarre and embarrassing", stating that he was "shocked" the party would declare Joachim Gauck their main enemy due to his investigation of communist injustice. Gabriel also said that the "reform forces" in the Left Party should stop "backing down" and "start enforcing their views".
The left-wing party The Left nominated Luc Jochimsen, a member of parliament and former editor-in-chief of public broadcasterHessischer Rundfunk. After her nomination, Jochimsen opined that the German Democratic Republic was not a "state of injustice", despite "committing inexcusable injustice towards its citizens". She withdrew after the second ballot, and urged her party members to abstain in the third ballot.
After the first two ballots, Christian Wulff led vote totals but could not win an absolute majority of 623 votes. It was notable that 45 delegates belonging to the governing coalition either voted for Gauck or abstained altogether during the first round. Thus, the vote went to a decisive third round, where only a plurality of votes was required to win. The election is the third to require three ballots since the current system was introduced in 1949.
Aftermath
A day after the election, a statement by Left Party politician Diether Dehm comparing the choice between Wulff and Gauck to a choice between Adolf Hitler and Joseph Stalin sparked controversy and drew criticism from Greens politician Renate Künast. Dehm subsequently apologized for his choice of words. Künast also stated that any future cooperation with the Left was "miles away", particularly in light of the party's rejection of Gauck. The SPD and Greens also blamed The Left for the election of Christian Wulff. Gysi, on the other hand, criticized the SPD of not cooperating with his party, which is considered extreme by federal authorities, and again pointed out differences in political positions between Gauck and the Left. On 2 July 2010 Wulff was sworn into office as President of Germany.
