The purpose of political action committees (PACs) is to raise and spend money to influence elections and legislation. PACs pool contributions from individuals or corporations to support candidates or initiatives that align with their interests. They play a crucial role in the American political landscape by financing campaign efforts, organizing grassroots support, and mobilizing voters. While they can enhance political participation, PACs also raise concerns about the influence of money in politics and potential corruption, prompting ongoing debates about campaign finance reform and transparency.
