House Bill 868 amends Tennessee Code Annotated to introduce restrictions on political campaign contributions from out-of-state entities. Specifically, it prohibits political campaign committees that are headquartered or domiciled outside of Tennessee from making contributions to candidates in primary elections, to other political campaign committees for related activities, or for any purpose intended to influence a primary election within the state. This new regulation aims to limit external influence on local electoral processes.

The bill defines "primary election" as any state or local primary election held in Tennessee for a statewide political party, and it specifies that a "statewide political party" refers to the party in control of both houses of the general assembly as of July 1, 2025. The act is set to take effect on July 1, 2025, emphasizing the importance of local governance in electoral financing.
