Berlin voters elect state parliament with CDU and Linke leading tight race

Electoral framework and voter rules

Approximately 2.5 million eligible voters in Berlin head to the polls on Sunday to elect the Abgeordnetenhaus, the city-state parliament, alongside local assemblies across all 12 administrative districts. Voters cast two ballots: one for direct candidates in 78 single-member constituencies and a second vote for party lists that determines overall parliamentary seat distribution. The parliament has a baseline size of 130 seats, though overhang and leveling mandates expanded the outgoing legislature to 159 seats. A 5% threshold applies to second votes to prevent parliamentary fragmentation and maintain legislative stability.

This election introduces voting rights for 16- and 17-year-olds in the state parliament race, a demographic comprising roughly 2% of eligible voters that previously held voting rights only at the district level. European Union citizens residing in Berlin are also eligible to vote in the borough assembly elections. The field of contenders has narrowed significantly compared to the prior race, with 17 parties presenting lists, down from the 33 parties that competed in the court-ordered 2023 repeat election.

Leadership upheaval in the governing CDU

The Christian Democratic Union (CDU) enters the vote defending its status as the senior partner in the governing coalition formed with the Social Democratic Party (SPD) in 2023. Governing Mayor Kai Wegner is not standing for reelection after resigning as the CDU top candidate in July. Wegner stepped down following disclosures regarding inaccurate statements he made about his administration's crisis management during an extensive power outage in January.

The CDU subsequently selected 46-year-old Berlin Finance Senator Stefan Evers to take over the top spot on short notice. Evers previously managed Wegner's election campaign three years earlier and now leads the party ticket into the state contest.

Challengers across the political spectrum

Polls place the CDU in a tight contest with Die Linke, led by 45-year-old lawyer Elif Eralp. Eralp, a mother of two who previously served in the background as deputy parliamentary group leader, has centered her platform on housing policy, campaigning to stop "Miet-Abzocke" (rent rip-offs) and make Berlin "wieder bezahlbar" (affordable again). She concurrently confronts internal party controversies regarding accusations that several pro-Palestinian activists within Die Linke hold openly antisemitic stances.

The SPD changed its leadership lineup by sidelining former Governing Mayor Franziska Giffey in favor of Steffen Krach. Krach's candidacy has encountered scrutiny following an investigation initiated by prosecutors in Hannover into the initial suspicion of accepting undue advantages during his tenure as regional president in Hannover, allegations that Krach has rejected.

Coalition prospects and federal context

Polling projections indicate that no two-party alliance, including the sitting CDU-SPD coalition, currently commands enough support to establish a governing majority. Die Linke and the CDU lead the field in close proximity, followed by the Green Party, the Alternative for Germany (AfD), and the SPD. The contest follows recent electoral gains by the AfD in Saxony-Anhalt, directing attention toward the Berlin result. Berlin votes on Sunday simultaneously with the state parliamentary election held in Mecklenburg-Vorpommern.
