Pro-Duterte partisanship climbs to 37% in June WR poll

MANILA — Support for the Dutertes and their allies rose to 37% in June 2026, up 4 percentage points from March 2026, according to the WR National Poll: Philippine Public Opinion Monitor released by nonpartisan firm WR Numero Research.

The findings reveal Filipinos’ self-identified partisanship, another dimension to the early election survey that the firm pioneered in 2024.

Respondents were asked how they characterize their support.

The Marcoses and their allies recorded 18% support, down 4 percentage points from March.

Some 20% declared support for the opposition side, including Naga City Mayor Leni Robredo, Sen. Risa Hontiveros, Sen. Bam Aquino, and their allies. This went up 3 percentage points from March 2026.

Almost a fourth of the respondents said they supported none of the above, at 24%, down 1 percentage point from March 2026. Some 2% refused to answer.

Among registered voters in the Philippines, 45% are in Luzon, 21% in the Visayas, 23% in Mindanao, and 11% in the National Capital Region.

The accompanying regional breakdown shows pro-Duterte partisanship at 80.49% in the Visayas, 34.94% in Mindanao, 21.56% in Metro Manila, and 19.25% in the rest of Luzon.

Pro-Marcos partisanship stood at 23.51% in Metro Manila, 22.73% in the rest of Luzon, 17.63% in Mindanao, and 5.5% in the Visayas.

Pro-opposition partisanship was highest in the rest of Luzon at 26.65%, followed by Mindanao at 24.01%, Metro Manila at 21.7%, and the Visayas at 1.76%.

Respondents who chose none of the above accounted for 32.38% in Metro Manila, 28.57% in the rest of Luzon, 20.81% in Mindanao, and 10.7% in the Visayas. Refusals were at 2.79% in the rest of Luzon, 2.61% in Mindanao, 1.56% in the Visayas, and 0.85% in Metro Manila.

The distribution of self-identified political affiliations varied across survey waves.

In the March 2025 WRN National Poll, 38% owned their pro-Duterte stance. It was highest the following month, April 2025, at 40%, before dropping to its lowest at 29% in August 2025. It went up again to 34% by November 2025, before dropping 1 percentage point to 33% in the March 2026 survey, and up in the June poll.

The pro-Marcos group remained relatively stable across survey periods, showing modest variation over time within the 15% to 22% range. The results are 15% in March 2025, 15% in April 2025, 19% in August 2025, 15% in November 2025, 22% in March 2026, and 18% in June 2026.

Opposition supporters exhibited greater variation across survey periods, recording a 14-point spread. The highest support was in the March 2025 survey at 26%, with a decline to 14% recorded a month later, followed by 16% and 12% in August and November of 2025.

It gained the most with an 8% increase from November 2025 to June 2026 and has steadily increased since, marking 17% in March and 20% in June this year.

Non-aligned or no-faction respondents consistently represented at least one-fifth of the sample. The results are 21% in March 2025, 31% in April 2025, 36% in August 2025, 39% in November 2025, 25% in March 2026, and 24% in June 2026.

No groups showed a consistent upward or downward trajectory across the six survey periods.

As each survey wave is based on an independent representative sample, differences should be interpreted as changes in aggregate sample composition rather than individual-level shifts, the firm said.

The June 2026 nationwide survey was conducted from June 9 to 16 through face-to-face interviews with a nationally representative sample of 1,432 Filipinos residing in the Philippines. The survey has a ±3-percentage-point margin of error at the 95% confidence level.

At the subnational level, the margin of error is ±7 percentage points for the National Capital Region, ±4 points for the rest of Luzon, and ±6 points each for the Visayas and Mindanao, all at the same 95% confidence level.

The latest WR National Poll also includes current public opinion on the performance of officials and institutions, pre-election preferences for the 2028 presidential, vice-presidential, and senatorial elections, the impeachment proceedings of Vice President Sara Duterte and trust in the Senate, Sen. Bato dela Rosa’s ICC case, constitutional amendments, effects of rising fuel and energy costs, effects of the US-Iran war on the economy, international relations, and trusted sources of information.
