Taipei mayor Chiang Wan-an filed his re-election papers alongside a slate of KMT city council candidates, projecting party unity — while an expelled former KMT youth figure attacked his record on the same day.

• Chiang registered his candidacy with KMT council hopefuls in a show of blue-camp unity.
• Ting Yu, recently kicked out of the KMT, called Chiang's running of the city a mess.
• Ting says police deliberately held him back from a press area, calling it proof Chiang blocks public opinion; he had agreed to a delayed slot but was kept waiting past the agreed time.
• Chiang's pitch is his record: opening the Taipei Dome and the concert economy it brought, landing Nvidia in Taipei, urban renewal plans, and six MRT lines including the new Xinyi extension.

Outlook: Expect the mayor's race to sharpen into a fight between Chiang's infrastructure record and challengers hammering his handling of dissent.
