KMT's commanding market position stems from its 14 incumbencies across Taiwan's 22 magistrate and mayoral races entering the November 28, 2026 local elections, reinforced by sustained coordination with the TPP on joint nominations in key districts and legislative initiatives such as simultaneous national referendums on nuclear power and absentee voting. This opposition alignment has consolidated anti-DPP support in most localities, while the DPP's five seats from 2022 and limited local organizational strength constrain its ability to mount broad gains despite holding the presidency. TPP's diminished viability further limits fragmentation of the opposition vote. Scenarios that could realistically shift probabilities include major candidate scandals, unexpected shifts in cross-strait tensions altering voter priorities, or last-minute breakdowns in KMT-TPP cooperation that split the field in pivotal races.
