Former Taiwan People's Party legislator Li Chen-hsiu has abruptly announced a bid for mayor of Zhubei, reigniting a dispute over her eligibility to run because of her Chinese nationality — bad news for the TPP.

• Li was previously expelled from the TPP over her Chinese nationality and controversial remarks, and is now making a run at the Zhubei mayoralty as an independent.
• She could end up facing the TPP's own candidate, Chiu Chen-yuan, creating infighting within the blue-white camp.
• International studies scholar Yeh Yao-yuan criticised the move as knowingly breaking the law, and called on the Central Election Commission to step in and address her registration eligibility.
• TPP legislator Chen Chao-tzu said she respects Li's right to take part in politics, but also publicly questioned whether Li can register at all.

Outlook: Whether the Central Election Commission accepts her registration will be the focus of attention, and the dispute could further erode the TPP's seat count in the midterm elections.
