Representative Erwin Tulfo ranked third with 53.50%, favored primarily by voters from Northern, Central, and Southern Luzon. While Ben Tulfo was more popular with younger voters aged 18-25, Erwin Tulfo had stronger backing from older respondents. Meanwhile, Senator Bong Go secured second place with 54%, showing notable growth compared to the previous month, particularly leading in Mindanao.
