A Super PAC, or "Political Action Committee," is a type of organization in the United States that can raise and spend unlimited amounts of money to support or oppose political candidates. Unlike traditional PACs, Super PACs are not allowed to coordinate directly with candidates or their campaigns. They primarily focus on independent expenditures, such as advertisements and other forms of communication. Super PACs emerged after the 2010 Supreme Court decision in Citizens United v. FEC, which ruled that spending money to influence elections is a form of protected free speech. This has led to significant increases in campaign spending, often resulting in Super PACs playing a major role in elections at both state and federal levels.
