Overview

• The BSW state organization reports about 900 members in Brandenburg, up from its 2024 founding.
• Müller said she chose BSW because it prioritizes people’s concrete concerns and called the step a deliberate decision.
• The longtime SPD member left the party in autumn 2024 after more than 25 years, citing Olaf Scholz’s Schwerin speech as her breaking point.
