Chiang Wan-an maintains a leading market position in the November 28 Taipei mayoral election due to KMT incumbency advantages in a traditionally supportive city, despite recent polling tightening. A late-October surge for DPP challenger Puma Shen produced leads in some surveys, but post-October 31 debate results showed Chiang ahead overall at 46 percent to 42 percent, with stronger support among non-viewers. Shen's gains stem from policy outreach on urban renewal, water resources, and defense priorities, plus backing from President Lai Ching-te. Minor candidates including Kuo Hsi remain marginal. Traders appear to weigh Chiang's infrastructure record and cross-party endorsements against the narrow polling gap and undecided voter shifts ahead of election day.
