A Political Action Committee, or PAC, is a private group organized to provide funding for political campaigns or the promotion of legislation that would benefit the group members. Almost every business and special interest group in the United States has a Political Action Committee to make sure its voice is heard by those making decisions that affect the group’s interests. PACs exist across the political spectrum. There are PACs devoted to doctors, teachers, builders, senior citizens, veterans, hospitals, automobile dealers, the arts and more.
