CDU drops out of Mecklenburg parliament and loses Berlin as AfD and Die Linke advance

Defeat in Mecklenburg-Western Pomerania

On 20 September 2026, the Christian Democratic Union (CDU) recorded its lowest regional election result since the founding of the Federal Republic in 1949. In Mecklenburg-Western Pomerania, a north-eastern state bordering Poland, the party dropped from 23.3% to 4.9%, failing to clear the 5% electoral threshold required for parliamentary entry. The loss marks the first time that the CDU has failed to secure representation in a German state legislature. The state had served for more than 15 years as the home constituency of former chancellor Angela Merkel. Alternative for Germany (AfD) placed first with between 37% and 38.2% of the vote, doubling its 2021 performance, while the Social Democratic Party (SPD) finished second with between 35.5% and 36.5%. Speaking at party headquarters in Berlin shortly after vote tallies were confirmed, Chancellor Friedrich Merz addressed the loss.

There is no point in trying to hide the results in Mecklenburg-Western Pomerania; it is a disaster.

Left-wing victory and shifts in Berlin

In the city-state of Berlin, Die Linke finished in first place for the first time, securing between 25% and 26% of the vote. The CDU fell 8.2 points to 20%, relinquishing its leadership of the capital's regional government. The Green Party received 15.5% of ballots, the AfD reached 13.5% after doubling its previous capital result, and the SPD dropped 6.4 points to 12%, its lowest total in Berlin history. Both federal governing parties campaigned with replacement candidates appointed late in the cycle. CDU candidate Stefan Evers assumed leadership two months prior following the forced resignation of Governing Mayor Kai Wegner over misleading statements regarding a tennis match played during a Berlin power outage. SPD candidate Steffen Krach, who led the Hannover regional administration for five years, entered the vote burdened by a judicial investigation made public 11 days before balloting.

Federal standing and reforms

The dual defeats occurred two weeks after the 6 September 2026 ballot in Saxony-Anhalt, where the CDU lost nearly 20 points and AfD approached an absolute majority. Following that earlier outcome, AfD co-leader Alice Weidel predicted the CDU would not win another federal election. Despite mounting pressure across three consecutive regional defeats, Chancellor Merz announced that he will remain in office as party chair and head of the federal government. Merz insisted on advancing federal economic reforms to revive growth, describing the measures as the remedy against authoritarian poison entering society. Public support for the chancellor has deteriorated, with national survey figures showing that 14% of Germans consider Merz suitable for the chancellorship.

Government formation and parliament balance

The election results leave the two traditional governing parties excluded from leading positions in both regional administrations. In Mecklenburg-Western Pomerania, AfD cannot form a government because all rival parties maintain a refusal to negotiate or govern alongside the group. Current Minister-President Manuela Schwesig of the SPD is positioned to retain office through a potential three-party coalition with Die Linke and the Greens. In Berlin, Die Linke lead candidate Elif Eralp is preparing to negotiate a majority alliance alongside the Greens and the SPD, ending the CDU's role in the capital's executive. While the voting does not change the seat distribution in the federal Bundestag, it consolidates gains by Die Linke and AfD at opposite ends of the political spectrum.
