Support for Taiwan's three major political parties all declined in the latest monthly survey, with the Taiwan People's Party (TPP) taking the steepest fall — sinking 4.2 percentage points to just 6.3%, its lowest level since Z. Media began continuous polling in October 2024.
The survey was commissioned by Z. Media and conducted by Mountain Water Public Opinion Research from August 15–17, 2026. It sampled 1,070 registered citizens aged 20 and above — 534 via landline and 536 via mobile — and carries a margin of error of approximately three percentage points at a 95% confidence level. Results were weighted for geographic region, gender, age, and education using Interior Ministry population data.
DPP Leads but Sheds 3 Points
The ruling Democratic Progressive Party (DPP) retained the top position among party supporters at 34.7%, though it shed 3.2 points from the previous survey. The main opposition Kuomintang (KMT) stood at 19.3%, down a marginal 0.2 points. Together, the three parties could claim only about 60% of public affiliation — the remaining 35.7% of respondents said they support no party.
The TPP, founded as a centrist alternative to Taiwan's two dominant parties, has struggled to maintain relevance amid sustained internal turmoil. The latest figures suggest the party's support base continues to erode rather than stabilize.
Pan-Green Bloc Leads Blue Camp by 15 Points
When asked about broader political leanings rather than specific party support, respondents identifying as pan-green — a coalition aligned with the DPP and broadly supportive of Taiwan's sovereignty — made up 36.7% of the electorate, down 3.7 points from the previous period. Pan-blue supporters, broadly aligned with the KMT and warmer cross-strait relations, came in at 21.8%, a decline of 2.8 points — leaving a gap of 14.9 percentage points between the two camps.
Independent and centrist voters stood at 36.6%, nearly matching the pan-green share — a figure that underscores how much of the electorate remains unmoored from the island's established party structures.
