**Tsai Yi-yu holds a commanding position in the Chiayi County Magistrate race as the Democratic Progressive Party nominee, with traders assigning the outcome an implied probability near 91 percent ahead of the November 28 vote.** The DPP has maintained consistent strength in this county, where the outgoing magistrate completed two terms, and Tsai secured a decisive primary victory in January 2026 that unified party resources. Recent central government endorsements, including appearances by former President Tsai Ing-wen and senior officials highlighting infrastructure investments, have reinforced his campaign focus on healthcare networks, agricultural modernization, and industrial parks. The main challenger, independent Wu Pin-jui, has emphasized elderly welfare subsidies and cross-regional cooperation but faces structural headwinds in a DPP-leaning electorate. A minor independent candidate trails far behind. Late developments such as scandals, sharp shifts in turnout among key townships, or unexpected national political events could still alter the race before election day.
