Chen Ting-fei of the Democratic Progressive Party holds a commanding lead in the November 28, 2026 Tainan mayoral race, backed by consistent polling advantages of 20–37 points over Kuomintang candidate Hsieh Lung-chieh. She secured the DPP nomination after a January primary victory and maintains strong support across most districts, age groups, and voter blocs, aided by high name recognition and endorsements from party leaders. Tainan’s long DPP control since the late 1990s reinforces her position. Hsieh focuses on governance issues and opposition coordination, yet trails significantly in favorability and projected winner metrics. Minor candidates register negligible support. Late developments such as turnout shifts or scandals could still affect final margins, though current trader consensus reflects the scale of Chen’s structural and polling edge.
