Taiwan's ruling DPP is putting its two biggest names behind Su Chiao-hui's run for New Taipei mayor, a sign the party sees the race as winnable but tight with 100 days to go.

• Su's campaign headquarters will hold its launch rally on September 5 in Banqiao, with President Lai Ching-te and former president Tsai Ing-wen both attending.
• Tsai has agreed to chair the campaign, a heavyweight endorsement in a city that gave her majority support in 2016 and 2020.
• Su appeared with all 36 DPP city council candidates at a temple blessing, framing the local elections as a team push for New Taipei.
• The party is leaning on its economic record and Lai's plan to hand every citizen a NT$10,000 cash payout next year.
• Su is pitching an inclusive, "colorful" vision for the city and touting backers from film, sport, and theater.

Outlook: Expect a full-court DPP press in New Taipei over the next three months, with the September 5 rally setting the tone for the year-end local elections.
