A single-issue group in politics is an organization that focuses exclusively on one specific area of concern, such as environmental protection, gun control, or healthcare reform. These groups mobilize advocacy efforts to influence public policy and raise awareness about their chosen issue. By concentrating their resources and efforts on a single cause, these organizations can often galvanize public support, engage in targeted lobbying, and sway political discourse. However, their narrow focus may limit their influence compared to broader coalitions that address multiple interconnected issues.
