Taiwan's two main opposition parties are moving toward a formal alliance ahead of the 2026 local elections, a threat to the ruling DPP.

• Taichung mayor Lu Shiu-yen floated an "opposition grand alliance," and both the KMT and the TPP quickly backed it.
• KMT Tainan mayoral candidate Hsieh Lung-chieh and TPP chairman Huang Kuo-chang opened a joint blue-white service center in Tainan and campaigned together.
• The stated goal is simple: remove the DPP from power, with shared resources and joint rallies across the city.
• Tainan has been a DPP stronghold for decades, so flipping it would signal a much wider shift — "if Tainan turns, Taiwan wins," as Huang put it.
• The TPP is running four city council candidates in Tainan and says its districts look competitive.

Outlook: Expect more joint KMT-TPP campaign machinery in other cities as the 2026 races take shape, with cooperation on single candidates the key test.
