SB 1040 would prohibit political campaign committees based outside Tennessee from making contributions (including non-cash donations) to influence primary elections for the Republican Party in Tennessee. It bans out-of-state committees from contributing to candidates or other committees aiming to affect these primaries, with specific definitions for "primary election" and "statewide political party" (determined by which party controls both legislative chambers after July 1, 2025). The bill would take effect July 1, 2025, if enacted. This directly affects out-of-state campaign groups and Tennessee candidates in Republican primary elections.
