Die Linke wins Berlin state election with over 25% of the vote as CDU and SPD lose ground
Die Linke has taken first place in the 2026 Berlin state election behind lead candidate Elif Eralp, while the governing CDU and SPD suffered losses amid shifting voter alignments and strong youth support for the left.
Left party takes first place
Die Linke finished in first place in the Berlin state parliament election on 20 September 2026, securing more than 25% of the second-vote share. The result followed weeks of close head-to-head polling between the leading contenders for the state legislature. Projections placed Die Linke clearly ahead of the Christian Democratic Union (CDU), while the Alternative for Germany (AfD) ran narrowly ahead of the Greens. The Social Democratic Party (SPD) experienced a sharp decline in its vote share compared to prior contests. Lead candidate Elif Eralp successfully mobilized the party base across multiple districts, ending the previous balance of power in the city.
Setbacks for the governing coalition
The election followed a period of leadership turbulence within the ruling grand coalition composed of the CDU and the SPD. Governing Mayor Kai Wegner of the CDU did not stand again as his party's top candidate following scrutiny over false statements regarding his crisis management during a municipal power outage. Voters evaluated both the performance of the outgoing Senate and competing proposals on core urban issues, including housing market conditions, local childcare facilities, education, and healthcare provision. Voter migration models compiled by Infratest Dimap tracked notable outflows from the two governing parties to rival groups and the non-voter bloc. The inability of the CDU and SPD to retain previous supporters opened the path for alternative governing majorities in the state assembly.
- CDU gains in outer districts while Greens lead in the central city during the previous state election.
- Governing Mayor Kai Wegner decides not to run as lead CDU candidate after blackout crisis management controversy.
- Die Linke wins over 25% of the vote in the Berlin state parliament election under Elif Eralp.
Generational divide in voting choices
Demographic data from Infratest Dimap exit polling pointed to substantial disparities in party preference across age groups in the German capital. Every second voter in the youngest demographic cast their ballot for Die Linke, establishing the party as the dominant choice among young citizens. In contrast, support for the CDU stood at under 10% among the youngest voters, compared to approximately 35% among the oldest cohort. Similar generational divides surfaced in neighboring Mecklenburg-Vorpommern, where the SPD registered only half as much support among younger demographics as it did among the oldest voters. The data demonstrates that traditional voter loyalties are concentrated increasingly among older age cohorts.
Structural erosion of traditional voter bases
Rüdiger Schmitt-Beck, a political scientist at the University of Mannheim, pointed to a broader structural decline in core party allegiance for Germany's traditional Volksparteien. As older, party-bound voters pass away, incoming generations of voters demonstrate far weaker long-term ties to specific political organizations. Schmitt-Beck described how these changing loyalties alter regional electoral balances.
There are more frequent changes leading to shifts from election to election in which party is the strongest.
Schmitt-Beck explained that changing voter dynamics leave established centrist parties vulnerable to competitors with sharper programmatic profiles, such as the Greens and Die Linke, or anti-establishment groups like the AfD.
The classic catch-all parties in particular are hit hard by this process.
In recent elections, including Berlin in 2023, voter decisions aligned heavily with specific salient issues, such as law and order in the outer districts for the CDU and climate and transport policy in the city center for the Greens.
