The US Supreme Court has torn down a crucial safeguard against unregulated party spending, striking at the heart of America's electoral system. In a long-awaited decision, the high court effectively repealed a decades-old restriction on 'coordinated party expenditures', allowing political parties to funnel unlimited funds into federal campaigns in direct support of their candidates.
The landmark ruling comes as part of National Republican Senatorial Committee v Federal Election Commission, a lawsuit filed by JD Vance and fellow Republicans Steve Chabot and the NRSC in 2022. They challenged the FEC's enforcement of limits on what are termed 'coordinated party expenditures', arguing that these constraints were redundant given the already minimal restrictions on Super PACs.
This latest ruling is the culmination of a two-decade trend, as the US Supreme Court has progressively dismantled restrictions on political donations and spending. Key precedents include the 2010 Citizens United v FEC decision, which abolished federal limitations on corporate spending by independent groups influencing elections, followed in 2014 by McCutcheon v FEC, striking down aggregate limits on individual contributions to candidates and committees.
The implications are far-reaching for UK interests. The erosion of campaign finance restrictions has led to an influx of 'dark money' into US politics, with the potential for foreign funds to seep into American campaigns via backdoor channels. This may raise concerns among British businesses, particularly those involved in transatlantic trade and investment.
The FEC has been rendered powerless, lacking a quorum since April 2025 and unable to enforce laws regulating campaign finance. External counsel was appointed to represent the organisation during the case, with Roman Martinez arguing that ending limits would legitimize 'quid pro quo' corruption and undermine democratic institutions. However, the court ultimately sided with the plaintiffs, paving the way for unlimited party spending in federal campaigns.
