A fight over how Taipei mayor Chiang Wan-an's son won an exchange-student place has turned into a political brawl ahead of the city's mayoral election, and it looks bad for Chiang.

• The city education bureau granted Chiang's son an exchange-student spot, raising questions about favoritism and whether Chiang should have stepped back from the decision.
• The KMT says the government is ganging up on Chiang, pointing to education, anti-corruption, and oversight bodies all looking into it.
• Puma Shen, the DPP's candidate for Taipei mayor, rejects that and mocks the KMT's reasoning as hard to follow.
• His argument is simple: the rules on disclosure already exist, so either they were followed or they were not.
• Shen says the boy's own ability is not the issue and accuses the KMT of hiding behind a child to score political points.

Outlook: Expect the disclosure question and the official reviews to keep driving the Taipei mayoral race in the coming weeks.
