Taipei's local election field is set after registration closed, with a two-way mayoral fight and unusually crowded council races that will leave many incumbents out of a job.

• Incumbent mayor Chiang Wan-an of the KMT faces the DPP's Puma Shen in the headline race, with four minor-party and independent candidates also on the ballot.
• 98 people are chasing 61 council seats across eight districts, so more than a third will lose.
• The tightest race is Shilin-Beitou, where 20 candidates fight for 12 seats and eight will fall short; Da'an-Wenshan, Zhongshan-Datong and Zhongzheng-Wanhua are also packed.
• Several retiring councillors are handing their seats to family members or protégés, keeping local political dynasties in place.
• Councillors from both major parties who were hit by corruption cases are running as independents, adding an unpredictable element.

Outlook: The mayoral contest looks like a straight KMT-DPP duel, while the crowded council races should squeeze out small parties and weaker incumbents.
