PUBLIC trust in the Senate sharply declined following its recent leadership shake-up, while confidence in the House of Representatives remained steady after it impeached Vice President Sara Duterte, the latest nationwide survey conducted by Tangere showed.
The noncommissioned survey, conducted from May 12 to 13, found that satisfaction with the Senate dropped to 29 percent from 44 percent recorded during the same period in 2025. Dissatisfaction with the chamber climbed to 51 percent.
The survey also showed trust ratings for the Senate falling to 27 percent, while 52 percent of respondents said they distrusted the institution.
A large majority of respondents, or 83 percent, believed the recent Senate leadership transition was politically motivated. Only 37 percent expressed support for the leadership change.
In contrast, the House of Representatives maintained a 51-percent satisfaction rating and a 52-percent trust rating during the same period. Negative sentiment toward the lower chamber also eased, with dissatisfaction declining to 29 percent and distrust dropping to 30 percent.
The survey period coincided with the House decision to proceed with the second impeachment complaint against Sara Duterte.
Tangere said 52 percent of respondents supported the impeachment, while 37 percent opposed it.
Support for the impeachment was strongest among respondents ages 25 to 50 years old from Luzon and Visayas. Opposition, meanwhile, was largely driven by respondents in the same age group from Mindanao.
The survey also measured public opinion regarding Sen. Ronald Dela Rosa and the arrest warrant issued by the International Criminal Court.
Results showed that 52 percent of respondents believed Dela Rosa should surrender to the National Bureau of Investigation. Support for surrender was strongest in Luzon and Visayas, while opposition came largely from Mindanao, where 57 percent of respondents said they disagreed with the move.
“These results show that Filipinos care deeply about how our government is run,” Tangere Chief Executive Officer Martin Peñaflor said.
“When people feel that changes in leadership are just about playing politics instead of actually serving the public, they lose faith in the Senate. This is reflected in the sharp contrast with the House of Representatives, where ratings remain steady despite making heavy decisions like the impeachment of the vice president,” he added.
Peñaflor also said growing public skepticism over the Senate’s recent moves appeared to be driving distrust toward the institution.
The survey used a mobile-based respondent application and covered 1,200 participants nationwide through stratified random sampling with quota-based sampling. It had a margin of error of ±2.77 percent at a 95-percent confidence level.
Respondents were distributed across the country, with 12 percent from the National Capital Region, 23 percent from Northern Luzon, 22 percent from Southern Luzon, 20 percent from the Visayas and 23 percent from Mindanao.
