Interest groups shape public policy outcomes by advocating for specific causes, influencing lawmakers, and mobilizing public support. These entities, including non-profits, labor unions, and business associations, often possess resources and networks that allow them to engage efficiently in the political process. Through lobbying, grassroots campaigns, and public education, interest groups can promote their agendas and sway policymakers to enact legislation favorable to their objectives. Consequently, their involvement can enhance representation of diverse interests, although it may also raise concerns about inequality in political influence.
