Former president Tsai Ing-wen is taking a hands-on role in the DPP's New Taipei mayoral campaign, a boost for candidate Su Chiao-hui ahead of the vote.

• Tsai has agreed to chair Su Chiao-hui's campaign headquarters, a high-profile endorsement in a city the DPP has long struggled to win.
• Su said Tsai promised to help whenever needed, not just lend her name to publicity.
• Tsai is expected to return to New Taipei often in the final stretch for meetings, events, and rallies.
• Su is framing the race as a chance for New Taipei to turn a page politically.

Outlook: Expect Tsai to appear more frequently on the campaign trail as election day nears, with the DPP betting her popularity can flip a traditionally tough district.
