Vice President Sara Duterte has emerged as the leading candidate for the 2028 presidential elections, according to a non-commissioned survey by Oculum Research and Analytics.
The survey, conducted from June 25 to June 30, shows that Duterte holds a 25.4% voter preference, placing her at the top of the list of potential presidential candidates. However, this marks a significant drop from the 42% voter preference she received in the first quarter.
Senator Raffy Tulfo ranks second with 18.5% voter preference. Following him are former Vice President Leni Robredo at 10.6%, Senator Imee Marcos at 5.7%, ex-Manila Mayor Isko Moreno at 4.8%, and ex-Senator Manny Pacquiao at 3.1%.
Senator Risa Hontiveros is in seventh place with 2.9%, Senator Robin Padilla at 2.6%, and House Speaker Martin Romualdez at 0.8%.
Approximately 20.4% of respondents remain undecided, while 4.3% indicated 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,” stated Dr. Racidon Bernarte, Oculum Research Head and Managing Director of the Asia-Pacific Consortium of Researchers and Educators Inc. (APCoRE).
“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,” added Bernarte.
For the vice-presidential race, Tulfo leads with 20%, followed by former President Rodrigo Duterte at 16%, Robredo at 7%, Moreno at 6%, and Hontiveros also at 6%.
Other potential vice-presidential candidates include:
- Senator Bong Go: 5%
- Senator Robin Padilla: 4%
- Ex-Senator Manny Pacquiao: 4%
- Senator Imee Marcos: 4%
- Speaker Martin Romualdez: 1%
Undecided respondents account for 22%.
