Grassroots lobbying involves mobilizing ordinary citizens to advocate for specific policy changes, demonstrating public support for issues. This approach emphasizes participation from the community rather than relying solely on professional lobbyists. Grassroots campaigns can include activities like organizing rallies, petitions, and social media outreach to raise awareness and influence policymakers. By showcasing widespread public sentiment, grassroots lobbying aims to pressure legislators to consider the constituents' views, making it an essential component of democratic engagement and civic activism.
