A federal court ruling striking down decades-old limits on political party spending is expected to unleash a surge of GOP campaign cash into Maine’s closely watched U.S. Senate race between Democrat Graham Platner and Republican incumbent Susan Collins. The Supreme Court voted 6-3 on Tuesday to eliminate caps on how much political parties can spend in coordination with candidates, reversing a more than 50-year-old federal election law.
Justice Brett Kavanaugh wrote in the majority opinion that the spending limits violated the First Amendment. “The combination of the statutory base limits, earmarking rules, and disclosure requirements are sufficient to prevent circumvention of the base limits,” Kavanaugh argued, according to the Bangor Daily News. The decision was hailed by President Trump and national Republican groups as a free speech victory.
The ruling stemmed from a 2022 lawsuit brought by then-Senator JD Vance and the National Republican Senatorial Committee challenging the Federal Election Campaign Act, a post-Watergate law. Trump’s Justice Department declined to defend the limits, leaving the Democratic National Committee to argue the other side.
Maine’s Senate race is already one of the nation’s most expensive, with nearly $500 million in total ad spending projected statewide. The court’s decision immediately amplifies that spending advantage for Republicans. In the week ending Monday, June 30, GOP groups spent $4.3 million on the Platner-Collins race, while Platner’s campaign and allied groups spent $1.6 million combined, according to The Hill. Collins’ campaign alone spent $500,000 during that period, while PACs supporting her spent $3.7 million.
The previous federal cap on coordinated party spending for Maine Senate races was just under $153,000. With that limit now gone, Republican operatives said plans are already underway to raise and allocate resources to competitive states. “Mainers were already going to be inundated with ads. Now it’s going to be [that] they can’t even go to the bathroom without seeing an ad,” said Brent Littlefield, a Republican strategist, according to the Bangor Daily News.
Republicans have reserved more than $107 million in ads for the Maine race compared to Democrats’ $55.5 million, according to Maine Morning Star. The Republican National Committee said the limits had undercut the party’s ability to support candidates. “The RNC has been preparing for this ruling, and we are ready to expand the ways we directly help and provide resources to Republican candidates across the country,” RNC Chairman Joe Gruters said, per the Bangor Daily News.
Why Maine’s Race Matters
The ruling comes as Platner’s campaign warned that outside GOP spending is vastly outpacing Democratic efforts. In a memo obtained by Politico and reported by The Hill, Platner’s team noted that GOP groups planned to outspend Democrats 4-to-1 over the upcoming week, with Pine Tree Results PAC alone planning to spend roughly $1.5 million weekly and nearly $10 million more by early August.
Political science experts say the advantage likely flows to Republicans. “Big picture, that’s probably going to be a bigger advantage for the Republicans than it is for the Democrats, just because Republicans have relied more on that kind of spending,” said Mark Brewer, chair of the political science department at the University of Maine, according to Maine Morning Star. The Republican National Committee has far more cash on hand than the Democratic National Committee: more than $125 million as of May compared to Democrats’ $14 million.
Platner criticized the ruling and Collins’ party support for it. “Collins and the out-of-state billionaires funding her campaign are terrified of what we’re building here in Maine,” Platner said in a statement to Maine Morning Star. “That’s why her party keeps turning to the courts to dismantle campaign finance laws and make it even easier for special interests to drown out the voices of the rest of us.”
The decision continues a two-decade pattern of the Supreme Court expanding First Amendment protections for money in politics. Citizens United v. FEC in 2010 removed restrictions on independent super PAC spending. This week’s ruling removes the final major constraint on party committees themselves, allowing them to raise unlimited funds while still coordinating with candidates—a power super PACs never had.
Platner has said he supports overturning Citizens United and is backing a legal effort using Maine law to challenge the foundation of that earlier decision. Collins’ campaign said it was still reviewing Tuesday’s ruling. Despite the spending edge, recent polling shows the race remains competitive, with The New York Times/Portland Press Herald/Siena University survey finding Platner at 49 percent and Collins at 47 percent among likely voters, within the margin of error.
