The purpose of a political action committee (PAC) is to raise and spend money to influence elections and policymaking. PACs are typically affiliated with corporations, labor unions, or interest groups, and they support candidates who align with their objectives. By contributing to campaigns or funding issue advertisements, PACs amplify their voices in the political process. They are subject to regulations regarding contribution limits and disclosure, which aim to promote transparency. Ultimately, PACs play a critical role in shaping political landscapes by mobilizing resources and advocating for specific agendas.
