Political action committee

A political action committee (PAC) is an FEC-registered entity organized to elect political candidates and lobby government. Traditionally, there were two distinct PAC types; separate segregated funds (SSF) that are administered by corporations, labor unions, membership organizations or trade associations, and nonconnected committees that are not sponsored by entities and are free to solicit contributions from the general public.

As a result of the Citizens United v. FEC decision in January 2010, "SuperPACs" have emerged for the Presidential Election 2012 to allow unlimited spending in support of or opposition to a candidate, as long as the SuperPAC operates completely separate and independent from the candidate. The influence of "SuperPACs" has eclipsed the significance of traditional PACs in elections.
