Fifty years of campaign finance law, gone in one ruling

On the last day of its term, the Supreme Court did something that will reshape how every competitive House and Senate race in the country gets funded. On June 30, 2026, the justices struck down federal limits on how much political parties can spend in direct coordination with their own candidates, ending a restriction that had stood since the post-Watergate reforms of the Federal Election Campaign Act, according to the Associated Press's coverage carried by PBS NewsHour. The vote split 6-3 along ideological lines, with all six conservative justices in the majority.

The case, National Republican Senatorial Committee v. Federal Election Commission, was brought by Republicans including sitting Vice President JD Vance, who had challenged the limits back in 2022 while running for Senate in Ohio, alongside former Rep. Steve Chabot. Their argument: capping how much a party committee can spend working directly with its own candidate amounts to the government restricting political speech, since spending money to support a candidate is itself a form of expression protected by the First Amendment.

What the old rule actually restricted

The law being struck down drew a specific distinction that mattered enormously in practice. Political parties could always spend unlimited amounts supporting a candidate through what's called an "independent expenditure" — money spent on ads or organizing that isn't coordinated with the campaign itself. But coordinated spending, where the party works hand-in-hand with the candidate's own operation, was capped. According to figures from the Federal Election Commission cited by CBS News, those caps for the 2026 cycle ranged from $65,300 to $130,600 for House campaigns, and from $130,600 up to roughly $4 million for Senate races, depending on the state's population.

That distinction mattered because coordinated spending is simply more valuable to a campaign than independent spending. The Hill's reporting on the ruling noted that coordinated expenditures typically secure lower advertising rates than a super PAC or outside group would pay for the same airtime, meaning the same dollar goes further when a party and its candidate work together rather than separately. Removing the cap doesn't just lift a dollar limit — it hands parties access to a more efficient spending mechanism than they've had in over five decades.

Kavanaugh's reasoning, and what he says still protects against corruption

Justice Brett Kavanaugh, writing for the majority, framed the ruling as a matter of fairness across the political spectrum rather than a partisan favor. Whether it's the Democratic Party, the Republican Party, or any other party, he wrote, all political parties and candidates can now compete under identical rules and structure their fundraising and spending as they see fit within the law. Kavanaugh argued that other safeguards remain in place to prevent quid pro quo corruption or its appearance — individual contribution limits, disclosure requirements, and rules against donors earmarking contributions to parties for specific candidates. He described these overlapping protections as "prophylaxis upon prophylaxis upon prophylaxis," suggesting the coordinated spending cap was one redundant layer among several, not the last line of defense.

Justice Samuel Alito, part of the majority, pushed back on how the decision has been characterized publicly, calling it "much maligned" and, in his view, unfairly so. That framing matters because it signals the conservative bloc sees this as continuous with, not a radical departure from, the court's Citizens United lineage — a body of case law that has steadily dismantled campaign finance restrictions since 2010 on First Amendment grounds.

Kagan's dissent: a checking account with no limit

Justice Elena Kagan, joined by Justices Sonia Sotomayor and Ketanji Brown Jackson, wrote the dissent, and her central image was blunt: with no limits on coordinated expenditures, she wrote, the party can effectively serve as the candidate's checking account. Her warning wasn't about theoretical corruption — it was about a practical mechanism for wealthy donors to route unlimited money to a specific candidate by giving to the party instead, sidestepping the individual contribution caps that still technically exist.

Kagan argued the ruling leaves behind "a legal regime increasingly unable to stop political corruption," and that disclosure rules alone won't surface the kind of backdoor arrangements the coordination limits were originally designed to prevent. Justice Sotomayor, during oral arguments back in December, put the broader pattern more plainly: "Every time we interfere with the congressional design, we make matters worse." That's a direct challenge to the majority's premise — that courts are better positioned than Congress to judge which anti-corruption measures are actually necessary.

Why this lands harder on one party than the other, for now

The ruling is formally symmetrical — it applies equally to the DNC, RNC, and every other party committee in the country. But its practical impact isn't symmetrical today, and both sides know it. The Hill reported that the Republican National Committee closed out May 2026 with $125 million cash on hand, compared to just under $15 million for the Democratic National Committee over the same period. Republican fundraising has increasingly flowed through the party apparatus itself, while Democratic money has tended to concentrate with individual candidates and outside groups. Lifting the coordination cap hands an immediate structural advantage to whichever party's committees are better capitalized — and right now, that's the RNC.

Trey Trainor, a former FEC chairman now with the Dhillon Law Group, called the decision a restoration of common sense, arguing that a party cannot meaningfully "corrupt" the very candidate it nominated in the first place. The DNC's response, issued through Chair Ken Martin alongside Representative Suzan DelBene and Senator Kirsten Gillibrand, called the ruling a win for billionaire donors and accused Republicans of rewriting the rules ahead of a midterm cycle where Democrats believe the political wind is at their back. Whichever framing proves more persuasive to voters, the practical reality is that party committees nationwide are now free to coordinate spending with their candidates at whatever scale their fundraising allows — a genuinely new fundraising landscape just four months before the 2026 midterms.
