Ko Wen-je acknowledged that the Taiwan People's Party has struggled to build support in southern Taiwan and publicly appealed to the Kuomintang's Hsieh Lung-chieh for help, indicating that blue-white cooperation is a necessity rather than a choice for the TPP.

• The TPP's Tainan candidates registered as a group, including four city council candidates and one village chief candidate.
• Ko Wen-je said bluntly that the TPP holds only one incumbent council seat south of the Zhuoshui River, that making inroads there has been an uphill effort, and that it needs Hsieh Lung-chieh to campaign on its behalf.
• The collapse of blue-white cooperation in the Zhubei mayoral race is seen as "the tip of the iceberg," with the KMT taking a cool stance and the two sides lacking any coordination mechanism.
• Ko Wen-je said that if the TPP cannot grow in this year's elections, Taiwanese politics will be left with nothing but a "contest of who is worse," with opposition parties unable to hold the ruling party to account.
• Former legislator Li Chen-hsiu, originally a citizen of mainland China, has announced a run for mayor of Zhubei; Ko Wen-je called on the Central Election Commission and the Mainland Affairs Council to clarify the standards governing the political participation rights of spouses from mainland China.

Outlook: Coordination between the blue and white camps in the local elections is likely to remain stalled, and whether the TPP can break out of its single-seat predicament in the south will be a key indicator in this year's campaign.
