Taiwan's former president is putting her name behind the DPP's candidate for New Taipei mayor, a boost for the party with local elections about 100 days away.

• Tsai Ing-wen has taken the top role at Su Chiao-hui's campaign headquarters.
• The two visited a temple in Banqiao together, drawing a large crowd of supporters.
• Tsai said New Taipei needs a better mayor and that Su would do the job better than her father, former premier Su Tseng-chang — and better than Tsai herself.
• The endorsement also covers the DPP's slate of local council candidates in New Taipei.

Outlook: Expect Tsai to keep campaigning across New Taipei as the DPP tries to flip a city it has long struggled to win.
