Multiple challengers, including SPD nominee Robert Alferink, Green candidate Volker Bajus, Die Linke’s Thomas Groß, and AfD’s Thorsten Wassermann, fragment the field and prevent any single opponent from consolidating broad support. Recent party nominations and candidate announcements have clarified the lineup without major shifts in positioning, leaving traders pricing in Pötter’s structural edge while assigning meaningful probability to a runoff or surprise contender performance in the final campaign stretch.
