The emergence of social media has significantly reshaped the political communication landscape, influencing voter behavior, electoral choices, and political engagement. This study explores the role of social media platforms such as Facebook, Instagram, and Twitter in shaping the political decisions and participation of registered voters in San Jose Del Monte, Bulacan. Using a descriptive phenomenological research design, the study investigates how social media impacts political endorsement, election surveys, and public opinion formation. Data was collected through interviews with registered voters, focusing on their experiences with political content, misinformation, campaign advertisements, and political discussions. Findings indicate that while social media is a powerful tool for political mobilization and awareness, it also contributes to the spread of misinformation and the reinforcement of ideological echo chambers. The study highlights the dual effect of social media: enhancing political participation while fostering political divisiveness. The results emphasize the need for improved digital literacy and stronger regulations to ensure the responsible use of social media in political campaigns. The study’s findings provide valuable insights for policymakers, political strategists, and scholars in understanding the evolving dynamics of voter behavior in the digital age.
