What is a PAC? A PAC is a political committee that raises and spends money to elect or defeat candidates. Most PACs represent businesses, such as the Microsoft PAC; labor unions, such as the Teamsters PAC; or ideological interests, such as the EMILY’s List PAC or the National Rifle Association PAC. An organization’s PAC will solicit money from the group’s employees or members and make contributions in the name of the PAC to candidates and political parties. Individuals contributing to a PAC may also contribute directly to candidates and political parties, even those also supported by the PAC. [Read More About the definition and history of PACs]
