Overview
- The SPD stepped into the contest on Friday, October 23, pressing for a quick nomination and explicitly naming Ilse Aigner as an acceptable successor to Frank‑Walter Steinmeier.
- CSU leader Markus Söder has publicly promoted Aigner for weeks and used the party congress in Munich to voice strong support for her candidacy.
- CDU leadership and Chancellor Friedrich Merz have pushed back against the idea of a pre‑emptive CSU appointment and have not yet decided whom the CDU will back for Bellevue.
- Analysts and CDU critics say electing Aigner as president would likely undercut Markus Söder’s future chancellor prospects because two top federal posts held by Bavarian CSU figures would be politically awkward.
- The dispute is expected to play out at the CSU party congress, where Merz will speak and party negotiations will determine whether the Union presents a united candidate ahead of the Bundesversammlung vote scheduled for January 30.
