The voting rights focused firm Law Forward and former Democratic U.S. Sen. Russ Feingold filed an amicus brief Monday in a lawsuit brought by the National Republican Senatorial Committee to strike down a law that limits the amount of money political parties can contribute to individual candidates for office.

The lawsuit was initially brought in 2022 by two Republican candidates, including then-Sen. JD Vance. The 6th Circuit Court of Appeals rejected the Republican argument and now that decision is being appealed to the U.S. Supreme Court. The Court is expected to hear the case during its 2025-26 term, which began on Monday.

In the amicus brief, Feingold and Law Forward argue that the weakening of campaign finance laws over the past few decades has deeply harmed American democracy — making elected officials more responsive to the needs of their wealthiest donors, in or out of their states and districts, rather than their constituents.

“We don’t have to guess what will happen if additional campaign finance rules are torn up, we’ve already witnessed it in Wisconsin. Striking down these federal limits will remove guardrails that are necessary for a representative democracy to thrive,” Feingold said in a statement. “The erosion of regulations is responsible for an alarming increase in the amount of money flowing through elections, giving wealthy donors an outsized voice in the political process, reducing the public’s faith in their elected representatives, and diminishing voters’ willingness to continue participating in the political process.”

During his 18 years in the Senate, Feingold regularly focused on campaign finance issues, including the passage of the Bipartisan Campaign Reform Act, which is commonly known as McCain-Feingold and instituted a number of rules guiding the use of “soft money” by outside groups running ads to influence elections.

The Supreme Court’s decision in Citizens United v. FEC decision in 2010 weakened the law and the brief filed Monday argues the erosion of campaign finance rules has damaged the country’s politics and made its government vulnerable to corruption.

“For a representative democracy to thrive, elected officials must be responsive to their constituents and avoid even the appearance of corruption,” the brief states. “Campaign finance regulation exists to reinforce these guardrails. Yet, for years, opponents of regulation have persistently chiseled away at the limits established to prevent excessive campaign cash from corrupting our elections.”

The brief uses Wisconsin as an example, which since 2015 has not placed a limit on the amount political parties can give to candidates. That change has resulted in wealthy donors from Wisconsin and across the country giving maximum contributions to candidates’ campaigns while giving much larger donations to each candidate’s party — essentially using the party committee as a middleman to funnel millions of dollars into candidate accounts.

“With each election cycle, the total contributions made, especially for statewide candidates, grows at a shocking rate, incentivizing candidates to court the wealthiest donors,” the brief states. “And, as Wisconsin elections have drawn more and more national attention, the pool of prospective donors has expanded to include increasing numbers of millionaires and billionaires residing in other states. Thus, the cycle continues. The flood of money into Wisconsin’s elections has bred accusations of corruption and threatens to drown out — if not completely silence — the voices of average voters.”

The brief argues that the decision by Wisconsin Republicans in 2015 to weaken the state’s campaign finance laws resulted in a downward spiral that opened the floodgates to money pouring into high profile races — most notably campaigns for governor and state Supreme Court.

“Wisconsin’s experience shows exactly what happens when we eliminate these crucial guardrails,” Law Forward attorney Rachel Snyder said. “The wealthiest donors route massive contributions through political parties, effectively buying themselves significant access to and influence with both political parties and elected officials. This isn’t about partisan politics — it’s about preserving a democracy where average citizens’ voices aren’t drowned out by billionaires’ checkbooks.”
