Super PAC
Independent expenditure-only political action committees, commonly known as super PACs, are a type of political action committees (PACs) in the United States. Unlike traditional PACs, super PACs are legally allowed to fundraise unlimited amounts of money from individuals or organizations for the purpose of campaign advertising; however, they are not permitted to either coordinate with or contribute directly to candidate campaigns or political parties. However, in practice, restrictions on such coordination are considered flimsy and poorly enforced.
Super PACs are subject to the same organizational, reporting, and public disclosure requirements as traditional PACs. Many super PACs are candidate-oriented but some focus on specific issues, an industry, a piece of legislation or a federal administrative rule.
Super PACs were made possible by two judicial decisions in 2010: Citizens United v. Federal Election Commission by the U.S. Supreme Court and, two months later, the federal Court of Appeals for the D.C. Circuit decision in Speechnow.org v. FEC.
