A political action committee (PAC) is a tax-exempt organization that collects voluntary contributions and distributes those funds to campaigns to elect or defeat candidates running for federal, state, or local public office. PACs may also collect contributions to be used to influence the passage or defeat of state ballot initiatives, and state or federal legislation. The majority of PACs represent private businesses, labor unions, or particular ideological or political viewpoints.


Political action committees are among the most common sources of funding for campaigns in the United States. The function of a political action committee is to raise and spend money on behalf of a candidate for elected office at the local, state and federal levels.


A political action committee is often referred to as a PAC and can be run by candidates themselves, political parties or special interest groups. Most committees represent business, labor, or ideological interests, according to the Center for Responsive Politics in Washington, D.C.


The money they spend is often referred to as “hard money” because it is being used directly for the election or defeat of specific candidates. In a typical election cycle, political action committees raise more than $2 billion and spend nearly $500 million.
