What is one of the key functions of an interest group?

One of the key functions of an interest group is to influence decision-makers on public policy. Interest groups are organized entities that aim to promote specific issues, interests, or causes by advocating for particular policies or legislation. They lobby lawmakers, engage in grassroots campaigns, provide information and research to support their positions, and mobilize public opinion. By focusing their efforts on shaping policy decisions, interest groups play a critical role in the political process, contributing to a pluralistic democracy where diverse viewpoints can be represented and considered in policymaking. This ability to influence is fundamental to their role; unlike political parties, which aim to gain control of government, interest groups focus on affecting outcomes related to specific issues.
