What form of advocacy involves building community support to influence policymakers?

Grassroots advocacy is characterized by mobilizing community members and leveraging their voices to influence policymakers. This form of advocacy focuses on engaging the general public, encouraging them to express their opinions and take actions that can persuade decision-makers on specific issues. The effectiveness of grassroots advocacy lies in its ability to demonstrate to policymakers that there is significant public support for a particular cause, which can often sway their decisions and shape policy outcomes.

In grassroots advocacy, organizations usually facilitate community action through campaigns, rallies, public meetings, and grassroots organizing, ensuring that the policymakers understand the constituents' positions. By amplifying local voices and uniting community members around common goals, this approach fosters a strong sense of collective action that can effectively impact legislative and policy decisions.

The other options focus on different aspects of advocacy, such as formal lobbying or party-oriented approaches, which do not emphasize community engagement in the same way. Thus, grassroots advocacy uniquely centers on building community support to drive change.
