The latest non-commissioned opinion survey taken by Oculum Research and Analytics showed that Vice President Sara Duterte topped the list of preferred presidential candidates in the 2028 elections.
According to the survey, Duterte had a 25.4% voter preference, making her the top presidential contender in the survey.
However, support for her slid significantly compared to the 42% voter preference score she garnered in the first quarter survey.
Senator Raffy Tulfo ranked second in the latest poll with 18.5%. He was followed by former VP Leni Robredo at third with 10.6%, Senator Imee Marcos with 5.7%; ex-Manila Mayor Isko Moreno with 4.8%, and ex-Senator Manny Pacquiao with 3.1%.
Senator Risa Hontiveros trailed at seventh with 2.9%, Senator Robin Padilla at 2.6%, with House Speaker Martin Romualdez at ninth with 0.8%.
Around 20.4% of respondents said they were still undecided while 4.3% answered none of the above.
“Inday Sara Duterte emerges as the current frontrunner with widespread support, particularly in Mindanao. Senator Raffy Tulfo, while second overall, shows a broad appeal across various regions. Former VP Leni Robredo, although third, has concentrated support in Southern Luzon,” Dr. Racidon Bernales, Oculum Research Head and Managing Director of the Asia-Pacific Consortium of Researchers and Educators Inc. (APCoRE), said.
“The high percentage of undecided voters and those opting for none of the above highlights potential volatility and opportunities for candidates to sway the electorate as the election approaches,” Bernales said.
Meanwhile, Tulfo was named the top choice for vice-presidential candidates in the 2028 elections with 20%. He was followed by former President Rodrigo Duterte with 16%; Robredo with 7%; Moreno with 6%; and Hontiveros with 6%.
Senator Bong Go ranked sixth at 5%; Padilla was seventh at 4%; Pacquiao, eighth at 4%, and Marcos at 4%. Romualdez ranked ninth at 1%.
Around 22% of the respondents were undecided.
