Define "grassroots advocacy."

Grassroots advocacy refers to the mobilization of community support by ordinary citizens to influence public policy or decision-making. It emphasizes the power of individuals at the local level coming together to express their concerns, needs, or desires regarding political issues. This form of advocacy is often characterized by its democratic nature, as it relies on the collective action of everyday people rather than established organizations or high-profile political figures.

In this context, grassroots advocacy works by encouraging individuals to engage in activities such as contacting their elected officials, participating in rallies, or utilizing social media to spread awareness. This method focuses on creating a strong base of support from the community that can lead to significant impacts on policy and legislation.

The other options do not align with the essence of grassroots advocacy. Efforts by politicians to gain support do not represent grassroots movements, as they often stem from established power structures. Campaigning for large organizations typically involves top-down strategies rather than grassroots mobilization. Lastly, top-down initiatives for policy change suggest a hierarchical approach where decisions are made by those in power, which contrasts with the collaborative and community-driven essence of grassroots efforts.
