The concluding chapter synthesizes key findings from our nationwide study exploring social media’s impact on local public spheres in Hungary, highlighting Facebook’s critical role in sustaining and revitalizing community engagement. We argue that social media provides essential communication infrastructure, allowing local and national political discourse to coexist within an integrated digital public sphere. The study demonstrates that local digital publics are significantly shaped by national political dynamics, with national parties influencing local political engagement, particularly through mayoral communication during strategic mobilization periods. Despite its extensive community-building potential, the digital public sphere faces notable challenges, including socio-demographic disparities, algorithmic constraints limiting local content exposure, and reliance on a single platform—Facebook—that is gradually declining in significance. The chapter emphasizes the importance of political actors’ strategic use of social media, noting their cautious navigation of national political content to maintain local audience engagement. Finally, the authors call for further research to examine the evolving dynamics of digital local publics, particularly their adaptability to shifting platform landscapes and deeper exploration into content and participatory characteristics. The chapter concludes by underscoring the necessity of continued attention to the intersection of local politics, digital infrastructures, and community engagement in political communication research.
