SPD faces existential crisis as German voters abandon center-left party

The Social Democratic Party, Germany's oldest political force, is contracting in real time. Nationwide, it has fallen to 12% in the polls—trailing not just the far-right Alternative for Germany but also the Christian Democrats and the Greens. In some eastern states, the collapse is steeper still. In Saxony-Anhalt, where state elections loom, the SPD sits at 7 to 8% while the AfD commands 42%. The party risks dropping below the 5% threshold needed for parliamentary representation altogether.

Matthias Miersch, the SPD's parliamentary group leader, traveled to Saxony-Anhalt in late August for a 24-hour campaign push. He attended a fitness class, met with housing cooperatives and refugee integration groups, and spoke at the Rainbow Cafe in Magdeburg about his own identity as a gay man. The conversations centered on the party's traditional terrain: affordable housing, social support, poverty reduction, protection against discrimination. Yet the backdrop was unmistakable. At the cafe, decorated with flags reading "No Time for Nazis," residents spoke of open hatred in rural areas and fear of an AfD-led state government. The domestic intelligence agency has classified the AfD's Saxony-Anhalt branch as a confirmed right-wing extremist organization.

The SPD's problem is not that it lacks a message on these issues. The problem is that voters no longer believe the party can deliver. The party serves as the junior coalition partner in the federal government alongside Chancellor Friedrich Merz's Christian Democrats—a deeply unpopular arrangement. As labor minister and finance minister, party leaders Bärbel Bas and Lars Klingbeil are seen as having surrendered too much ground. The SPD has accepted cuts to housing benefits, the abolition of early retirement at 63, and stricter rules requiring doctor's notes from the first day of illness. On migration policy, too, the party has moved rightward. Critics within the SPD argue that these compromises have erased any clear political identity. "We have lost the trust of voters because, on many issues, the SPD was unwilling to ruffle feathers," Bas acknowledged after the first two state election defeats of 2026.

Those defeats were historic. In Baden-Württemberg, the SPD recorded its worst postwar result and barely held onto parliamentary representation. In Rhineland-Palatinate, after 35 years in power, the party was pushed decisively into second place by the CDU and suffered its worst result in the state's history. September 2026 threatens to bring more losses. In Berlin, the SPD languishes at 12%, in fifth place. In Mecklenburg-Western Pomerania, the party faces the prospect of losing power entirely. Five state elections across 2026 make it a super election year, and the trajectory is unmistakable downward.

The most damaging shift is among the party's historic base. According to Forsa polling from November 2025, only 9% of blue-collar workers and unemployed voters now support the SPD. An infratest dimap survey from February 2025 found that 38% of workers were voting for the AfD. These are not marginal movements. They represent the wholesale defection of the constituency that built the party into a mass movement. Workers who feel socially disadvantaged are increasingly drawn to the far right, not the center-left.

Internally, the party is fracturing. Orkan Özdemir, a Berlin state legislator and co-chair of the SPD's Working Group on Migration and Diversity, told the German Press Agency in early August: "I see a party that is dying." The group's leadership has called for a special party conference in autumn and a restructuring of party leadership. They are far from alone. Dissatisfaction that first surfaced after the initial state election defeats is now spreading throughout the party. Critics argue that the dual role of Bas and Klingbeil—serving simultaneously as party leaders and federal government ministers—is simply not working. The arrangement forces the party to defend federal government decisions that alienate its own members and voters.

Klingbeil has expressed understanding for the criticism while remaining measured. "We're at 12% nationwide, and these are extraordinarily turbulent times," he said during a campaign appearance in Saxony-Anhalt. "I know that some of the decisions made at the federal level are demanding a great deal from my own party, too." Yet his acknowledgment does not resolve the underlying question: what does the SPD stand for anymore? More and more Social Democrats are asking whether the party should exit the federal coalition and rebuild from opposition, accepting political irrelevance in the short term to recover a distinct identity. The alternative—remaining in government while hemorrhaging voters to the AfD—may be worse. The party that once counted every second German voter among its supporters now faces the prospect of becoming politically irrelevant.
