Political Action Committees (PACs) have been around since 1944. A PAC is a political committee organized for the purpose of raising and spending money to elect and defeat candidates. Most PACs represent business, labor or ideological interests. PACs can give $5,000 to a candidate committee per election (primary, general or special). They can also give up to $15,000 annually to any national party committee, and $5,000 annually to any other PAC. PACs may receive up to $5,000 from any one individual, PAC or party committee per calendar year. A PAC must register with the FEC within 10 days of its formation, providing name and address for the PAC, its treasurer and any connected organizations. Affiliated PACs are treated as one donor for the purpose of contribution limits. For more information, check out the FECs "Political Action Committees Guides"
Super PACs. Two federal court rulings in 2010 paved the way for the ascent of “super PACs,” political action committees that can raise and spend unlimited amounts of money on political races, as long as they don’t coordinate with a specific candidate. They do, however make independent expenditures in federal races - running ads or sending mail or communicating in other ways with messages that specifically advocate the election or defeat of a specific candidate. There are no limits or restrictions on the sources of funds that may be used for these expenditures. These committees file regular financial reports with the FEC which include their donors along with their expenditures. View the current list of super PACs.
