The National Republican Senatorial Committee argued before the Supreme Court on 9 December 2025 that limits on coordinated spending between political parties and their candidates violate the First Amendment 1. Current caps range from $127,200 to $3.9 million per Senate race, depending on state population. Those limits exist to prevent parties from functioning as unlimited conduits for donor money.
Striking them down would allow national party committees to spend without ceiling alongside a candidate's official campaign. The Campaign Legal Center warns this would render individual contribution limits largely irrelevant, since a donor could give the legal maximum to a candidate and then give unlimited additional funds through the party for coordinated spending on the same race. The distinction between party and campaign would dissolve in practice.
