The Supreme Court is expected to rule by the end of June in NRSC v. FEC, the National Republican Senatorial Committee's challenge to limits on how much a party committee can spend in coordination with its own candidates1. Those limits sit in the Federal Election Campaign Act (FECA), the 1971 statute that governs US campaign finance, and are enforced by the Federal Election Commission (FEC). The case was argued on 9 December 2025.
At argument, Justice Brett Kavanaugh said the caps had weakened parties relative to outside groups, and the conservative majority signalled it was ready to strike them2. The mechanism decides the stakes. Today a Super PAC, a group that raises unlimited money but cannot legally coordinate with a campaign, must run a parallel operation. That is why the Senate Leadership Fund, the main Republican Senate Super PAC, builds its own $342 million plan rather than handing the cash to candidates. An independent expenditure (IE) is spending that backs a candidate without the campaign's involvement, and the firewall between the two is what the caps police.
Strike the caps and the NRSC, the NRCC, the DSCC and the DCCC, the four party campaign committees, could all spend without limit in direct consultation with named candidates: same message, same targeting, no firewall. The Democratic committee-cash lead, the $12.6 million edge the DCCC banked over the NRCC, rests on the assumption that parties can spend only within the caps. Remove them and a fundraising advantage stops being a structural one, because Republicans could match it through direct coordination instead.
The Sixth Circuit, the federal appellate court for Michigan, Ohio, Kentucky and Tennessee, upheld the law before the Supreme Court took the case. The justices could rule narrowly rather than abolishing the limits outright, and the opinion had not issued at publication.
