Taiwan's ruling DPP is trying to land former president Tsai Ing-wen as campaign chair for its Taipei mayor candidate Puma Shen — a boost for the party if she agrees, but nothing is settled.

• With about 100 days left before Taiwan's local elections, the DPP wants Tsai to head Shen's Taipei campaign.
• Lawmaker Wang Shih-chien, already a deputy chair of the campaign, said the whole party hopes she takes it.
• Tsai has already chaired DPP campaigns in New Taipei, Taitung and Keelung, so the ask is not unusual.
• She has kept a low profile since leaving office and prefers a quiet private life, though she still follows politics closely.

Outlook: Tsai is expected to help if she has the time, but the decision and the timing of any announcement are hers alone.
