Claudius Siebert has emerged victorious in the mayoral runoff in Dorfen, securing 57.2% of the votes with a total of 4,305 ballots cast in his favor. The incumbent mayor, Heinz Grundner from the CSU, received 42.8% of the votes, tallying 3,224, which marks a significant decrease of 10.7% from his performance during the local elections six years ago. Siebert, a 50-year-old economic lawyer, ran for a coalition comprising the ÜWG, SPD, Greens, and the West List, highlighting a shift in local political dynamics.

Key issues that shaped the electoral campaign included traffic on the federal highway B15 that runs through the town, the upcoming railway extension from Munich to Mühldorf and the necessary noise protection measures, as well as the pressing concern over affordable housing. Since the introduction of the A94 highway, rental and property prices in the area have skyrocketed, which has become a focal point of community discussions. Additionally, there was controversy surrounding the relocation of sports facilities from the town center to the outskirts, which added to the heated election atmosphere.

The CSU and Grundner had long underestimated the political newcomer Siebert, a miscalculation that ultimately cost them the election. This change in leadership offers a potential shift in policy directions, especially regarding urban planning and community development in Dorfen, which may now take a different approach under Siebert's administration. The outcome reflects larger trends in local governance as residents express their priorities for their community's future, particularly in terms of infrastructure and housing.
