Taiwan's ruling Democratic Progressive Party mayoral candidate Su Chiao-hui holds a narrow three-point lead over Kuomintang rival Lee Shu-chuan in New Taipei City ahead of the November 28 local elections, a new poll shows. A survey by pro-KMT United Daily News released on Monday showed the 50-year-old legislator and daughter of former Premier Su Tseng-chang with 42 percent support. Lee, a 68-year-old engineer, trailed closely at 39 percent, with 19 percent undecided. The tight race threatens the KMT's two-decade grip on New Taipei, traditionally considered a blue stronghold since 2005. However, Lee's campaign director Chiang I-chen expressed confidence yesterday, noting the gap had narrowed from an October poll where Lee trailed by 13 percent. Chiang added that internal polls since May consistently showed Lee maintaining a steady lead, calling surveys a "scientific tool, not a campaign weapon." KMT New Taipei chairman Huang Chih-hsiung predicted a 60 to 65 percent voter turnout. He said Lee's victory hinges on mobilizing the existing KMT base while swaying centrist voters, youth, and supporters of the Taiwan People's Party – a smaller opposition party. Staff reporter
