**Tsai Yi-yu maintains a commanding lead in the Chiayi County Magistrate race ahead of the November 28, 2026 vote.** The Democratic Progressive Party legislator secured a decisive primary victory in January 2026 and benefits from strong party organization, endorsements from senior DPP figures including former President Tsai Ing-wen and President Lai Ching-te, and emphasis on continuing infrastructure, semiconductor-related economic growth, and an all-generation care network. His sole qualified opponent, independent Wu Pin-jui, has focused on targeted elderly welfare measures but lacks comparable institutional backing. With only two candidates on the ballot following qualification reviews, traders price in the structural advantages of the DPP’s local machinery and voter base, while noting that unusually low turnout could still introduce volatility before resolution.
