German voters cast ballots in Berlin and Mecklenburg-Western Pomerania as Friedrich Merz faces dual regional tests
Nearly four million voters will cast ballots in Berlin and Mecklenburg-Western Pomerania on Sunday, testing Chancellor Friedrich Merz following recent conservative setbacks.
High stakes across two regional votes
Nearly four million eligible German voters will participate in two regional elections on Sunday, 20 September 2026, casting ballots in Berlin and the northeastern state of Mecklenburg-Western Pomerania. Polling locations across both jurisdictions will remain open from 06:00 to 16:00 GMT, at which point authorities will release the initial exit poll estimates and projections. The double ballot takes place two weeks after the Alternative for Germany (AfD) defeated the Christian Democratic Union (CDU) in the Saxony-Anhalt state election. Facing political pressure from both the far right and the radical left, Chancellor Friedrich Merz, 70, cancelled his scheduled flight to New York for the United Nations General Assembly and called an extraordinary CDU crisis meeting for Sunday evening immediately following the close of polling.

Northern state contests and threshold pressures
In Mecklenburg-Western Pomerania along the Baltic coast, Minister-President Manuela Schwesig of the Social Democratic Party (SPD) seeks to retain executive office despite her party recording lowest levels in federal polling. Schwesig built her campaign around her regional governance record, gaining 18 percentage points over the preceding twelve months to move ahead of the AfD in the closing phase of campaigning. In contrast, the regional CDU list faces severe difficulties, with polling indicating that the party could fail to reach the mandatory 5% electoral threshold required to enter the state legislature. Political scientist Ursula Münch assessed the stakes for the conservative party in the northern contest.
If the CDU, for the first time in its history, failed to sit in a regional parliament, even if it is, in quotation marks, only a "small Land", it would of course be a disaster.
Federal tax measures and Berlin mayoral race
To address voter dissatisfaction before the weekend polls, the Merz administration announced a package on Friday, 18 September, lowering energy taxes on diesel and petrol while considering future retail fuel price caps. Attention also turns directly to Berlin, where 3.9 million residents could see a leadership transition at the Rotes Rathaus. Polls show Die Linke candidate Elif Eralp holding 22% of voter support, placing her in position to form a governing municipal coalition with the Greens and the SPD. Eralp adopted grassroots campaigning techniques modeled on those of New York City Mayor Zohran Mamdani, having enlisted his former campaign strategist.
Housing pressures and municipal proposals
Eralp focused her mayoral campaign primarily on residential housing, reflecting the circumstances of Berlin, where tenants comprise 85% of the local population. Average rents in the city escalated by more than 40% across the past decade, reaching 15.84 euros per square metre without utilities in early 2026 despite statutory rental controls established in 2015. Eralp's central campaign initiative proposes the municipal nationalization of 220,000 apartments held by profit-oriented corporate landlords, a measure supported by voters in a non-binding 2021 referendum. If exit projections materialize, Eralp will become the first far-left mayor to lead the capital administration since German reunification, reshaping the municipal government as federal parties evaluate the regional outcomes.
