Grassroots campaigns are initiatives that mobilize ordinary citizens to advocate for a particular cause or political candidate. They typically rely on community engagement and volunteer efforts rather than significant funding from elites. Grassroots movements use strategies like door-to-door canvassing, phone banking, and social media outreach to rally support and influence public opinion. These campaigns emphasize the power of collective action, often seeking to amplify the voices of underrepresented groups. By fostering community involvement, grassroots initiatives can drive social change and encourage greater political participation among citizens.
