The March 2025 Social Weather Stations (SWS) survey, commissioned by Stratbase Consultancy, revealed that senatorial candidates Senator Bong Go and ACT-CIS Rep. Erwin Tulfo continue to lead the senatorial race, each securing 42 percent of intended votes among registered voters.
The survey was conducted from March 15-20, using the list of 66 candidates based on the revised ballot face template released by the Commission on Elections (Comelec).
Go and Tulfo remain in a tie for first and second place, followed by television and radio personality Ben Tulfo and former senator Vicente “Tito” Sotto III, both with 34 percent of voter support, sharing third and fourth place.
Senator Lito Lapid holds fifth place with 33 percent, while Senator Ramon “Bong” Revilla Jr. is in sixth with 32 percent.
Other candidates with notable support include Senator Pia Cayetano and former senator Ping Lacson, who both garnered 31 percent, securing seventh and eighth spots.
Senator Ronald “Bato” Dela Rosa placed ninth with 30 percent, and television personality Willie Revillame rounded out the top 10 with 28 percent.
Meanwhile, Makati City Mayor Abby Binay, former senator Manny Pacquiao, and Las Piñas Rep. Camille Villar are tied in 11th-13th place, each with 27 percent.
Except for Lapid, who previously held the third spot, SWS said candidates in the top 12 maintained their rankings from the February 2025 survey.

The survey also reported that 7 percent of respondents either refused to answer, were undecided, or returned blank ballots.
Six percent of respondents made invalid marks, such as overvoting or improper shading, in their ballots.
The Stratbase-SWS March 2025 National Survey was conducted through face-to-face interviews of 1,800 registered voters nationwide.

The survey's sampling error margins are ±2.31 percent for national percentages, ±3.27 percent for Balance Luzon, and ±5.66 percent for Metro Manila, the Visayas, and Mindanao.
