Chang San-cheng’s commanding 92% market position stems from his incumbency as KMT mayor, sustained polling leads exceeding 20 points, and higher name recognition and favorability ratings compared with DPP challenger Huang Shih-chieh. Recent surveys from September 2026 showed Chang preferred by 47% of Taoyuan voters versus 25.9% for Huang, with strong resident satisfaction tied to infrastructure projects such as MRT expansions, the Taoyuan Aerotropolis, and Longtan Science Park growth alongside welfare initiatives. Huang’s campaign, backed by President Lai Ching-te, emphasizes local roots and generational change but has not narrowed the gap ahead of the November 28 vote. The two-candidate race limits fragmentation, reinforcing trader consensus around the incumbent’s structural advantages while leaving room for late developments such as turnout shifts or unforeseen events to alter the outcome.
