Democrats and Republicans offered starkly different reactions Tuesday after the Supreme Court struck down decades-old federal limits on how much political parties can spend in coordination with congressional and presidential candidates, a ruling expected to reshape campaign finance ahead of future elections.

The decision invalidated a provision of the Federal Election Campaign Act that had capped coordinated party spending for more than 50 years.

Writing for the 6-3 majority, Justice Brett Kavanaugh said, "More speech is generally better than less speech," concluding the limits violated the First Amendment.

The restrictions were originally designed to prevent wealthy donors from circumventing individual contribution limits by channeling money through political parties.

President Donald Trump praised the decision in a Truth Social post, calling it "A BIG WIN FOR REPUBLICANS" and "more importantly, The First Amendment!" He wrote: "The Supreme Court just took restrictions off political spending! A BIG WIN FOR REPUBLICANS and, more importantly, The First Amendment!"

Republican campaign leaders hailed the ruling as a constitutional victory.

"This is a decisive First Amendment victory and a major win for the integrity of our political system," NRCC Chair Richard Hudson and NRSC Chair Tim Scott said in a joint statement. They said the Court correctly found the government lacked authority to impose "arbitrary limits" on how parties support their nominees, adding the ruling restores "core political speech" and puts parties "in the strongest possible position to win in 2026 and beyond."

Democrats sharply criticized the ruling, arguing it will expand the influence of wealthy donors in federal elections.

"This is a win for billionaire donors and special interests who want more influence over the GOP agenda and an invitation for corruption," Democratic National Committee Chair Ken Martin and DSCC Chair Kirsten Gillibrand said in a statement.

Martin accused Republicans of "rewriting the rules" to "flood elections with more money from their billionaire backers," adding that voters would reject what he called Republican efforts to "rig the system and weaken our democracy."

The case stemmed from a 2022 lawsuit filed by the National Republican Senatorial Committee, the National Republican Congressional Committee and then-Sen. JD Vance of Ohio.

The Federal Election Commission later abandoned its defense of the law after President Donald Trump returned to office, while Democrat committees intervened to argue the limits should remain in place.
