Onyeka Oshionwu of Bündnis 90/Die Grünen secured 41.4% in the September 13 first round of the Göttingen Oberbürgermeister election, well ahead of Ehsan Kangarani (CDU) at 27.9%, with Florian Dinger (SPD) at 21.6% and Thomas Goes (Die Linke) at 9.1%. No candidate reached an absolute majority, triggering the September 27 runoff between the top two. Oshionwu’s margin reflects her local roots as a sitting deputy mayor, cross-party appeal, and the Grünen’s strong council performance, while the SPD’s failure to advance ended its long hold on the office. Trader consensus assigns her a dominant position ahead of the final vote, though outcomes remain subject to turnout shifts or last-minute mobilization between the two candidates.
