MANILA, Philippines — The alleged misuse of confidential and intelligence funds is the most widely identified impeachment charge against Vice President Sara Duterte, according to the latest National Momentum Survey released Tuesday.
The non-commissioned survey found that 38.7 percent of the 1,487 Filipino adults interviewed identified the alleged misuse of confidential and intelligence funds as an impeachment charge against Duterte but 35.3 percent said they could not identify any of the charges.
The survey was conducted from Aug. 18 to 23, 2026 through face-to-face interviews, while the prosecution was presenting evidence and witnesses on Article I of the impeachment complaint, which involves the alleged misuse of confidential funds.
Awareness of the other charges was considerably lower, with 14.6 percent identifying grave threats, 13.3 percent the alleged bribery involving Department of Education personnel, and 6.7 percent unexplained wealth.
The survey also asked respondents whether they considered the charges credible.
The confidential-fund allegation again ranked highest, with 28.2 percent saying they found it credible. This was followed by grave threats at 15.5 percent, unexplained wealth at 12.1 percent and bribery at 7.7 percent.
About 20.5 percent said none of the charges were credible, while 12 percent were unsure and 4 percent declined to answer.
The strongest regional divide emerged in Mindanao, where 34.7 percent of respondents said none of the impeachment charges were credible.
This was higher than the corresponding figures in Metro Manila at 23.7 percent, the rest of Luzon at 15.6 percent and the Visayas at 12.7 percent.
Mindanao also recorded the lowest share of respondents who considered the confidential-fund allegation credible, at 13.5 percent.
The figure was higher in Metro Manila at 34 percent, the rest of Luzon at 33.2 percent and the Visayas at 30 percent.
Awareness of the confidential-fund charge was highest in Metro Manila at 44.6 percent, followed by Mindanao at 40.2 percent, the rest of Luzon at 38.8 percent and the Visayas at 32.5 percent.
The survey also showed significant differences in perceptions across political groups.
The confidential-fund allegation was identified by 47.7 percent of pro-opposition respondents, 40 percent of pro-Marcos respondents, 39.8 percent of pro-Duterte respondents and 35.9 percent of independents.
Among pro-Duterte respondents, however, 36.6 percent said none of the impeachment charges were credible.
Only 17.9 percent of pro-Duterte respondents considered the confidential-fund allegation credible, compared with 44.5 percent of pro-opposition respondents, 37.9 percent of pro-Marcos respondents and 30.4 percent of independents.
Gen Z respondents had the highest awareness of the confidential-fund allegation at 43.4 percent, followed by millennials at 38.2 percent, Baby Boomers at 36.4 percent and Gen X at 33.9 percent.
Millennials had the highest share who said none of the charges were credible at 24.8 percent, followed by Gen X at 17.7 percent, Gen Z at 16.4 percent and Baby Boomers at 2.5 percent.
Gen Z respondents were also the most likely to consider the confidential-fund allegation credible, at 33.8 percent, followed by Gen X at 30.7 percent, Baby Boomers at 23.7 percent and millennials at 23.2 percent.
The survey had a national margin of error of plus or minus 2.5 percentage points at a 95 percent confidence level.
Its subnational margins of error were plus or minus 6.9 percentage points for Metro Manila, 3.8 percentage points for the rest of Luzon, 5.8 percentage points for the Visayas and 5.5 percentage points for Mindanao.
The survey noted that public awareness and perceptions of credibility could still change as respondents hear more evidence on the allegations involving unexplained wealth and bribery.
