Coalition-building is vital in politics as it enables diverse groups to unite around common goals or issues. By forming coalitions, organizations or political parties can increase their influence, resources, and likelihood of achieving policy objectives. This practice is especially important in settings where a single entity may lack sufficient power to enact change independently. Coalition-building promotes collaboration, enhances the diversity of ideas, and fosters solidarity among different stakeholders. It can lead to more robust public support and a greater chance of success in mobilizing for particular initiatives or legislations.
