Eight senatorial candidates backed by President Ferdinand "Bongbong" Marcos Jr.'s administration are leading the race, according to the latest Social Weather Stations (SWS) survey.

The survey, conducted from 17 to 20 January and sponsored by Stratbase Consultancy, revealed significant shifts in voter preferences for the 2025 senatorial elections compared to the December results.

Here’s a breakdown of the changes in public preferences for potential senatorial candidates:

ACT-CIS Representative Erwin Tulfo continues to dominate the race with 45 percent of votes, maintaining his lead from the previous survey. Former Senator Vicente "Tito" Sotto III climbed to second place with 38 percent, a notable improvement from his December ranking of fifth with 31 percent.

Senator Lito Lapid registered the most significant gain this month, jumping from 11th place to third or fourth place with 37 percent, a 14-percentage-point surge from last month's 23 percent.

Senator Christopher "Bong" Go held onto the third or fourth spot, increasing his support from 32 percent in December to 37 percent. Meanwhile, Senator Ping Lacson improved his ranking, rising from seventh to fifth place with 35 percent, up from 27 percent last month. Broadcaster Ben Tulfo remained steady in sixth place.

Senator Pia Cayetano, who previously ranked third or fourth with 32 percent, saw a slight uptick to 33 percent but dropped to seventh or eighth place, tying with former senator Manny Pacquiao, who moved up from eighth in the previous survey.

Makati Mayor Abby Binay secured the tenth spot alongside Senator Ronald "Bato" Dela Rosa, who climbed from 12th to 14th range last month, both garnering 30 percent.

Senator Bong Revilla suffered the biggest drop, falling from second place in December with 33 percent to the 11th to 13th range in January with 29 percent.

Former senator Francis "Kiko" Pangilinan re-entered the top 12 after jumping from 20 percent in December to 29 percent, tying with Revilla and TV host Willie Revillame, who slipped from eighth to ninth place and now shares the 11th to 13th spot.

Senator Imee Marcos, previously among the frontrunners, dropped out of the top 12, settling in 14th place with 28 percent.

The nationwide survey was conducted through face-to-face interviews with 1,800 registered voters aged 18 and above. As the midterm elections approach, Filipinos are set to elect 12 new senators and 63 party-list representatives on 12 May.
