The Tangere Senatorial Preferential Survey shows that Senator Bato Dela Rosa rose the highest, while Senator Bong Go remains alone at the top

 

According to Tangere’s most recent 2025 Pre-Election Senatorial Preferential Survey, Senator Bong Go was the only candidate to receive a 59.3% vote. According to voter preference, Senator Bong Go ranks among the top three in each of the nation’s seventeen regions. Erwin Tulfo, the representative for ACT-CIS, will come in second place with a voter preference of 55.1%, primarily from Northern and Central Luzon.

Sen. Bong Revilla, Media Executive Ben “Bitag” Tulfo, and Sen. Bato Dela Rosa will be statistically tied for third place. Millennial and Gen-Z voters preferred Ben “Bitag” Tulfo over his brother, who was preferred by the older respondents. Driven by strong support from Visayas and Mindanao, Sen. Bato Dela Rosa made a major leap in the survey, increasing his voter preference by over 10%.

Imee Marcos posted a 3.75% increase in her voter preference (statistically tied at 12^th -18^th with 33.5%). Interestingly, Sen. Marcos experienced a notable decline in Northern Luzon after the endorsement of the Vice President.
