Partisan political groups are defined in the Hatch Act as those groups that (1) are affiliated with a political party or candidate for public office in a partisan election, (2) are organized for a partisan purpose, or (3) engage in partisan political activity. Under (1), any organization that is recognized by a national or state political party as a club, auxiliary, authorized committee, or other affiliated organization is a partisan political group. Under (2), any organization formed to support or oppose one or more political parties—or a party's candidates for partisan political office—is a partisan political group. As for (3), OSC evaluates organizations on a case-by-case basis. When doing so, OSC considers several factors including, but not limited to, the following: the organization's stated purpose, as reflected in its bylaws or charter, on its website, and in its other public materials; whether the organization expends its resources on political activity; whether the organization prominently advertises its political activity; the relationship between the organization and its affiliates, if any, that engage in political activity, such as whether they share a website, staff, or office space; and whether the organization has indicated on any government filings that it engages in political activity.
