A commissioned survey conducted by OCTA Research from Sept. 30 to Oct. 4 revealed that ACT-CIS Party-list Rep. Erwin Tulfo is once again at the top of the list of potential senatorial candidates for the senate in the May 2025 elections.

Tulfo had a “significant” lead in the third quarter of 2023 poll results released on Monday, Oct. 23, with 60 percent of Filipinos saying they would vote for him in the next senatorial elections.

The survey had 1,200 adult respondents across the country.

Tulfo also led OCTA’s second quarter of 2023 survey, with 73 percent of Filipinos supporting him.

OCTA said Tulfo was joined mostly by current or former members of the senate in the latest survey.

“Among those with a statistical chance of winning, seven are incumbent senators, and three are former senators,” it pointed out.

Senator Christopher “Bong” Go claimed the second spot with a 49 percent voting preference.

Former Senator Vicente “Tito” Sotto III followed, with a voting preference of 42 percent (third to fifth place).

Meanwhile, Senators Imee Marcos and Ronald “Bato” Dela Rosa each received 39 percent of the overall voting preference (third to seventh place).

Senator Pia Cayetano and former Manila Mayor Francisco “Isko Moreno” Domagoso finished fourth to ninth, with 36 percent and 35 percent of the overall voting preference, respectively.

Former Senator Panfilo “Ping” Lacson and Senator Ramon “Bong” Revilla tied for sixth to 10th place, each with 32 percent of the overall voting preference.

Meanwhile, Senator Francis Tolentino has a 28 percent overall voting preference (8th to 12th place), followed by Senator Lito Lapid and former Senator Manny Pacquiao, both of whom have 26 percent and share the 10th to 13th places.

Completing the list of probable winners is physician Willie Ong with a 21 percent voting preference (11th to 18th spot).

Other notable figures on the list of top 20 candidates included former Senators Francis “Kiko” Pangilinan and Gringo Honasan and former Vice President Noli De Castro Jr., each with 19 percent of the voter preference.

National Defense Secretary Gilbert “Gibo” Teodoro followed closely with 18 percent, while former Senator Richard “Dick” Gordon received 16 percent.
