Final answer:
Compared with political parties, interest groups usually have limited issue concerns, focusing on specific areas such as economic issues, single-issues, or ideologies to influence public policy.
Step-by-step explanation:
Compared with political parties, interest groups usually have limited issue concerns. Interest groups are organizations that unite individuals based on common goals or concerns and aim to influence public policy through political action. Unlike political parties, which seek comprehensive political power and represent a broader range of issues and constituents, interest groups tend to focus on specific issues, whether they are economic, single-issue, ideological, or public interest-related. For example, the National Rifle Association focuses on gun rights, while the Brady: United Against Gun Violence advocates for stricter gun control measures.
Interest groups may have narrower membership bases than political parties and can either support or oppose political candidates based on how closely the candidates align with the groups' interests. Interest groups' goals are more issue-specific and they work to bring attention to these issues, sometimes using emotional appeals rather than logical arguments. While they do compete with political parties for influence, they also cooperate across party lines when it aligns with their interests.
