The Supreme Court Just Gave Political Parties Their Spending Power Back

The U.S. Supreme Court on June 30 struck down federal limits on how much political parties can spend in coordination with their own candidates, a 6-3 decision that hands the Republican and Democratic organizations financial leverage they have not held in decades.

The ruling in National Republican Senatorial Committee v. Federal Election Commission removes caps that, in 2026, ranged from roughly $130,600 to just over $4 million for Senate races, and $65,300 to $130,600 for House races, with the exact ceiling tied to a district's or state's population. Those limits capped what a party committee could spend jointly with a candidate. They are now gone.

Early coverage framed the outcome as another victory for big money in politics. The more consequential story is about who controls that money. For most of the past two decades, campaign finance rules pushed party spending toward the margins while empowering two other forces: small-dollar donors and independent political action committees.

Why the caps mattered

The post-Watergate reforms of the 1970s restricted party money in federal races. The McCain-Feingold law of 2002 extended those constraints to state-level party funds that could indirectly benefit federal candidates. The combined effect, as the writer David Frum argues in The Atlantic, was not to remove big money from politics but to reroute it into PACs and super PACs.

Two 2010 rulings accelerated that shift. Citizens United v. FEC at the Supreme Court and SpeechNow.org v. FEC at the D.C. Circuit freed those vehicles to spend without limit. PACs took over some functions parties once performed, including recruiting and vetting candidates, but with less transparency and less permanence. Party committees, meanwhile, were left with capped budgets and diminished influence over their own nominees.

The case against small donors

The conventional reform narrative casts the small-dollar donor as the antidote to wealthy interests. The evidence complicates that picture. Political scientists Zachary Albert and Raymond La Raja, in their book Small Donors in US Politics: Myth and Reality, warn that elevating small donors may correct one bias, the outsized influence of the wealthy, while worsening another, the growing influence of the most extreme voters.

Small donors, they note, tend to be more ideological and more partisan than the average voter, and generally wealthier as well. They gravitate toward candidates who perform well on television and social media, and often skip the downballot races that determine legislative majorities.

The list of politicians who have thrived on small-dollar money spans both parties: on the Republican side, figures including Ron Paul, Marjorie Taylor Greene, and Donald Trump; on the Democratic side, Alexandria Ocasio-Cortez and Bernie Sanders. In Maine's current Senate cycle, nearly 60 percent of contributions to candidate Graham Platner arrived in gifts under $200.

What restored party power looks like

With spending caps lifted, party committees regain a practical form of leverage: the ability not just to fund a candidate, but to withhold funding and redirect it elsewhere. National Democrats reportedly tried to steer Maine party members away from Platner as a Senate nominee. Under the new ruling, such guidance carries more weight, because a party can now credibly promise substantial support to candidates who follow its advice and shift resources away from those who do not.

Candidate quality has been a recurring problem for both parties, particularly in Senate contests. Republicans have watched winnable seats slip away with nominees such as Christine O'Donnell in Delaware in 2010, Todd Akin in Missouri in 2012, and Blake Masters in Arizona in 2022. This cycle, Frum argues, the difficulty has been sharper on the Democratic side, with the national party struggling to back more electable candidates in states including Maine and Michigan.

The deeper argument for stronger parties is institutional. Parties once absorbed hundreds of competing interest groups into two broad coalitions, brokered compromises, and mediated internal disputes that now spill into public view as spectacle. Neither PACs nor small donors have taken up that work. Whether returning money to the parties revives that mediating function is an open question, but the ruling removes a legal barrier that had stood for years.
