Final answer:
An interest group's main concern is to shape public policy through various means such as lobbying and advocacy.
Step-by-step explanation:
An interest group is mainly concerned with shaping public policy rather than with nominating candidates, addressing local issues, or winning national elections.
Interest groups are organizations formed to advocate for specific issues or causes, and their primary goal is to influence government policy and decision-making. They do this by working to shape public opinion, lobbying lawmakers, and engaging in direct advocacy efforts. Unlike political parties, interest groups focus on specific policies rather than winning elections or promoting a broad ideological agenda.
For example, an interest group advocating for stricter environmental regulations may work to shape public opinion through educational campaigns, lobby lawmakers to pass stricter legislation, and engage in direct advocacy efforts such as protests or public hearings.
