Publication 417, Nonprofit USPS Marketing Mail Eligibility: Nonprofit and Other Qualified Organizations > 5 Cooperative Mailings > 5-4 Political Committee Mailings
Qualified political committees are subject to the cooperative mailing requirements. However, unlike cases involving cooperative mailings between an authorized nonprofit organization and a commercial organization, there is often an ongoing relationship between the qualified political committee and the committee’s candidate.
A political candidate may be connected to the authorized political committee mailer by being a member of and/or financial contributor to the political party represented by the committee. The committee is, of course, interested in promoting, encouraging, and supporting the candidate’s election.
Postal laws and regulations do not prohibit the candidate from contributing to the committee or the committee from supporting the candidate. The concern under postal laws and regulations is whether the political candidate’s financial contribution to the authorized political committee is in return for the mailing or mailings that support the candidate.
