The chapter investigates how localized social media experiences influence political trust, satisfaction, and participation at local and national levels, using data from a nationally representative survey in Hungary. We test whether following local mayors, exposure to local politicians’ content, and participation in local Facebook groups can act as catalysts for enhanced political engagement and attitudes. Findings reveal that following mayors can boost trust and satisfaction with local political actors, particularly in larger municipalities, while exposure to local politicians’ content moderately enhances local political participation. Conversely, membership in local Facebook groups without active mayoral participation correlates negatively with political trust and satisfaction, suggesting active local political leadership is crucial in digital community spaces. At the national level, the catalytic role of local political participation is minimal. Experiences in local settings have little impact on political behavior at the national level. This suggests that voters perceive a sharper divide between local and national politics, and even under favorable conditions, localized social media experiences generate positive attitudes and increased activity that do not significantly influence their views or behavior regarding national politics.
