Interest groups significantly influence public policy formation through advocacy, lobbying, and mobilizing public support. By representing specific interests, these groups provide legislators with expertise, resources, and information on various issues. Their activities can shape policy agendas, affect decision-making processes, and mobilize constituents to advocate for particular legislative changes. While they can enhance democracy by amplifying diverse voices, they may also lead to imbalances when more powerful groups overshadow the concerns of less organized populations. Thus, the role of interest groups is pivotal in shaping the policy landscape.
