Merz’s CDU Faces Historic Defeat in Two State Elections
By Drooid · · How we work
Core Event
On September 20, 2026 exit polls showed Chancellor Friedrich Merz’s Christian Democratic Union (CDU) falling below the 5 % threshold in Mecklenburg-Western Pomerania and slipping to second place behind Die Linke in Berlin. The far-right Alternative for Germany (AfD) topped the vote in Mecklenburg-Western Pomerania with roughly 38 % and placed third in Berlin with about 16 %.
Background & Context
Merz assumed the chancellorship in May 2025, promising tax, welfare and bureaucracy reforms. Earlier that month, on September 6, 2026, the AfD won in Saxony-Anhalt with 43.8 %, signalling a shift in the former East German states. The CDU’s 4.9 % result in Mecklenburg-Western Pomerania is the first time the party has failed to clear the 5 % barrier anywhere in post-war Germany.
Data & Statistics
- Mecklenburg-Western Pomerania: AfD ? 38 % (reports vary 38.2-38.3 %), SPD ? 35 %–35.5 %, CDU 4.9 %.
- Berlin: Die Linke ? 25 %–25.7 %, CDU ? 18 %–20 %, AfD ? 16 %–16.3 %.
- Nationwide approval of Merz: 13 % (ARD poll) and 10 % (other poll).
- Unemployment: over 3 million, up 36 000 year-on-year (Federal Employment Agency).
Why It Matters / Impact
- The CDU’s exclusion from the Mecklenburg-Western Pomerania parliament weakens Merz’s bargaining power within the federal coalition with the SPD.
- AfD’s surge intensifies debate over the “firewall” policy that blocks cooperation with the far-right, raising the risk of a fragmented Bundestag after the 2029 federal election.
- Die Linke’s breakthrough in Berlin could reshape housing policy, as its platform includes rent caps and expropriation of large corporate landlords.
Official Statements & Responses
- SPD premier Manuela Schwesig warned that the AfD’s rise reflects voter frustration with federal reforms and affirmed her commitment to a “stable democratic government.”
- Die Linke leader Elif Eralp promised to make Berlin “affordable again,” proposing rent caps and the seizure of corporate housing assets.
- AfD co-leader Alice Weidel declared that the CDU has been displaced as the “people’s party” and urged the CDU to step aside.
Criticism & Opposition
- Alice Weidel (AfD) argued that Merz is the wrong chancellor for the CDU and is dragging the party down.
- Manuela Schwesig (SPD) attributed the AfD’s success to the federal government’s failure to deliver on pension reforms and energy policy, calling for a self-critical review of the CDU.
- Kerstin Münstermann, veteran journalist, described the situation as a genuine crisis of authority within the CDU.
On-the-Ground Reports
- Voter Carlotta Heick in Schwerin (Mecklenburg-Western Pomerania) told Reuters that wages are insufficient to cover living costs.
Conflicting Reports & Gaps
- AfD’s vote share in Mecklenburg-Western Pomerania is reported as 38.2 % (DW, Reuters), 38.3 %, and 38 % (other outlets).
- CDU’s Berlin percentage ranges from 18 % to 20 % and 19 %. Final counts are pending, leaving coalition negotiations uncertain.
What’s Next
- The SPD-Left-Greens alliance in Mecklenburg-Western Pomerania is expected to negotiate a governing coalition within weeks, with a formal formation deadline approaching.
- Berlin’s mayoral coalition talks will continue after Die Linke’s projected win, with a mayoral appointment likely before the end of October.
- The CDU is slated to hold a leadership meeting in early October; depending on the outcome, the Bundestag may face a confidence-vote discussion later in the year if the federal reform agenda stalls.
