In the 2022 midterms, the U.S. campaign finances were flooded by an unprecedented series of outside spending. In This Dark Money News Series we analyze and reveal how Super PACs, 501(c) “social welfare” groups and other external entities poured roughly $1.3 billion into House and Senate races by late October – “a record for a midterm election,” according to OpenSecrets data reported by NPR.
Overall expenditures on federal contests in 2022 are now projected to exceed $9 billion. That total is double the 2014 midterm outlay and a 32% jump from 2018, making 2022 the costliest congressional cycle in history.
Crucially, the lion’s share of this new money came not from party coffers or candidate committees, but from the shadows – from political machines outside official campaigns.
As one analyst put it, without the deluge of outside advertising “Republican candidates would be swamped on the airwaves”. Indeed, during the 2022 midterms nearly 86% of pro-GOP TV ad spending in the Senate races was financed by independent groups (only 55% for Democrats). In short, a tiny class of mega-donors and dark-money vehicles dominated the money race, amplifying their influence well beyond their numbers.
A Tale of Two Fundraising Worlds of Dark Money
Experts describe a bifurcated reality: one financial universe for party committees, another for outside groups. Federal law still imposes strict caps on donations to party organizations and candidates, but court rulings over the last decade have opened a wide portal for unregulated cash.
As law professors note, the 2010 Citizens United and SpeechNow decisions effectively permitted corporations, unions and individuals to give unlimited sums to Super PACs and nonprofits that run independent campaign ads.
The result is what campaign scholar Michael Toner calls “a tale of two fundraising stories”: on one side, candidates, Super PACs and allied nonprofits can accept unlimited contributions from any source; on the other, the official Democratic and Republican parties remain bound by tight federal contribution limits.
In 2022 this split was stark. Sabato’s Crystal Ball and the Campaign Finance Institute documented that party committees represented just 12–18% of all “outside” spending – their lowest share in decades – while Super PACs and 501(c) outfits gobbled up the rest.
This disparity has concrete effects. Super PACs and affiliated groups now routinely raise hundreds of millions each cycle from a handful of billionaires and corporations. In 2021–22, the ten richest donors to Super PACs (like Richard Uihlein, Jeffrey Yass, Stephen Schwarzman and Michael Bloomberg) collectively gave hundreds of millions apiece.
Unlike parties, these entities face no significant fundraising limits. Sabato and Trainer note that outside groups “can raise large amounts of money from a small group of donors in a very short period of time,” and today “are spending significantly more on independent expenditures … than [are] political party committees”.
In other words, the richest backers amplify their reach through these PACs and nonprofits, effectively writing their own check to party agendas.
The Mechanics of Dark Money
The channels for these funds exploit legal loopholes. By law, a Super PAC (or independent-expenditure PAC) cannot coordinate directly with candidates, but it may spend unlimited sums on ads and get-out-the-vote drives so long as it discloses its donor list.
However, a parallel system of 501(c)(4) and 501(c)(6) “social welfare” groups operates largely in the shadows. These nonprofits are allowed to engage in political campaigns as long as politics isn’t their primary purpose, but they are not required to name their donors.
As a result, money can flow into the campaign ecosystem where the public sees nothing: Super PACs often get funding from these non-disclosing groups, masking the ultimate source.
In short, big-money donors can hide behind a web of non-profits and LLCs. As one expert notes, with this structure “we don’t even know how much they [dark-money groups] are spending,” since both the donors and the full expenditures can remain opaque”.
2022 Dark Money Spending in Hard Numbers
The magnitude of outside spending in key races was staggering. In Senate contests alone, outside groups – largely Republican-aligned – poured nearly $1 billion into GOP campaigns by election day.
For example, the Senate Leadership Fund (aligned with Senate GOP leader Mitch McConnell) spent about $219 million across eight states, with roughly $110 million plowed into the three closest races in Georgia, Pennsylvania and Ohio.
By comparison, the top Democratic super PAC (Senate Majority PAC) spent about $145 million in six states.
Those ad buys and GOTV efforts helped keep vulnerable incumbents afloat and flipped other contests, despite the GOP ultimately falling one seat short of a Senate majority.
At the state level, those expenditures were concentrated in traditional swing battlegrounds. Public reporting shows the five states seeing the heaviest TV ad spending in 2022 were Georgia ($258M), Pennsylvania ($241M), Arizona ($213M), Wisconsin ($204M) and Nevada ($171M).
These sums include both campaign-funded and outside ads; in practice, a disproportionate share came from outside groups pushing partisan narratives. In each of these contests, dark-money war chests swamped local media markets with hundreds of ads per week by October, saturating voters’ screens with competing messages.
Though analysts have struggled to directly measure the turnout impact, one admitted that without the billion-dollar outside push, Republicans “would be swamped on the airwaves”.
Critics contend that much of this spending amounted to last-minute litmus-test messaging (frequently digital and in minority communities) whose primary purpose was persuasion or demobilization – outcomes that are hard to quantify but obviously hinge on the vast secret resources behind them.
Profiles of the Shadow Players of Dark Money
Several organizations stand out as bellwethers of the dark-money surge. On the right, Senate Leadership Fund and Congressional Leadership Fund dominate. SLF, backed by Sen. McConnell’s network, raked in and spent about a quarter-billion in 2022.
CLF, allied to then-House GOP leaders, deployed roughly the same order of magnitude. Conservative 501(c) nonprofits also played a role. For example, Americans for Prosperity (the Koch network’s flagship advocacy group) and its sister Super PAC averaged dozens of millions in major races, though granular data are limited.
Meanwhile American Action Network (a 501(c)(4) founded by Norm Coleman) quietly routed tens of millions more in conservative issue ads nationwide (its precise 2022 expenditures remain opaque). Another new entrant was One Nation Action, a conservative nonprofit bankrolled by a handful of GOP donors, which poured money into battlegrounds even as it did not formally file independent expenditure reports.
Together, these dark entities formed a decentralized “parallel campaign” for Republicans.
On the left, big-spenders included Senate Majority PAC and House Majority PAC (aligned with the Democratic leadership), which also raised and spent nine-figure sums. Liberal-leaning 501(c)(4) outfits such as Priorities USA Action and Future Forward USA amplified the mainstream campaigns.
Outside labor-oriented groups like NextGen America (affiliated with SEIU) funded voter outreach and climate ads in swing states. Even the League of Conservation Voters, officially an environmental membership group, sent hundreds of millions (via its PAC and 501(c)(4)) to defend incumbents on climate issues.
But by year’s end, one study found that all the top dark-money donors and groups heavily outweighed the grassroots: as Sabato’s team summarized, “Republicans and their dark money backers” combined to deliver unprecedented financial clout.
State-Level Impact: Dark Money Impact On The Swing States
The flood of dark money was felt keenly on the ground in the battleground states. In Georgia, millions of dollars from SLF and allied groups bought tens of thousands of local broadcast spots, reinforcing the GOP message in a state with a razor-thin margin.
In Pennsylvania and Wisconsin, secret-money armies circulated mailers warning of “election fraud” and linking Democrats to unpopular figures – often right up to Election Day. Arizona saw dark-money ads in Spanish and English alike, targeting Hispanic and independent voters on issues like border security and energy, funded by both sides’ outside groups.
Grassroots organizers reported that these ad blitzes created an atmosphere of high-stakes urgency and confusion, shattering normal debate with last-minute, high-volume hits.
Independent observers note a worrying pattern: because outside ads and mailers are not disclosed until after the election (if at all), voters see paid campaign messages but don’t know who financed them.
The Brennan Center has warned that many expenditures by “shadow parties” are timed or structured to evade disclosure. For instance, dark-money groups may postpone releasing their donor reports or run ads just below FEC reporting thresholds.
In practice, by the time the public learns of the hidden donors behind a smear ad or turnout campaign, the votes are cast and the horse race is over. This secrecy makes it virtually impossible to hold anyone accountable for misleading or disruptive messaging paid for by special interests.
The FEC’s (Non)Enforcement and Legal Loopholes
Despite the staggering expenditures, federal oversight of these flows was essentially nonexistent. The Federal Election Commission (FEC), responsible for enforcing campaign finance laws, has long been hamstrung by partisan gridlock and understaffing.
In early 2024, Senate Democrats labeled the FEC “dysfunctional” and “toothless,” noting that coordinated Republican efforts have left the agency mired in deadlock.
In practical terms, the FEC is six commissioners voting in a 3–3 split. As long as both parties have any commission seats filled, enforcement actions and new rules can be easily blocked.
The result is a near-total policy vacuum. Major ambiguities and loopholes remain: for example, there is still no federal rule treating bundlers (people who solicit campaign donations, or bundle small checks) as de facto donors, thanks to the FEC’s inability to advance such rules.
A recent analysis flatly declares that after a series of court decisions and Congress’s failure to act, “the financing of campaigns has returned once again to the Wild West,” with contribution limits easily evaded and regulation “grounded to a halt by a deadlocked FEC”.
Put another way, the referee is effectively off the field. Even routine FEC reports must be parsed by watchdogs; without intervention, secret money remains largely untracked.
This lack of accountability troubles reformers. As Tiffany Muller of the anti-corruption group End Citizens United put it, the moneyed interests “drowned out the voices of the American people” through unlimited and undisclosed donations, leaving the FEC unable to enforce the rules.
And indeed, with so much spending hidden, “we don’t even know how much they are spending,” as one Brennan Center expert notes.
These failures underscore how, by design or neglect, the post-Citizens United regime shields secret spending from public scrutiny and legal challenge.
Similar Dark Money Tactics Abroad: India’s Electoral Bonds
The United States is not unique in this struggle between money and transparency. In India, Prime Minister Narendra Modi’s government had pioneered its own version of dark-money conduits. Starting in 2018, India introduced electoral bonds – bearer instruments sold by state-run banks that ostensibly allow donors to give to political parties anonymously.
Though pitched as a reform, bonds have in practice become a black box. Journalists and scholars report that over $1.9 billion (US) has flowed through this system in recent years.
Nearly two-thirds of that money ended up with the ruling BJP (leading to allegations it rigged the funding playing field). Many of the bond contributors were shell companies or far-flung entities with little legitimate business – essentially placeholders to funnel cash into party coffers.
The Supreme Court of India itself has criticized electoral bonds for violating citizens’ right to know who funds politicians, labeling the current law a “systemic commercial bribery” scheme.
Still, without judicial or legislative fixes, India’s electoral bond mechanism had enabled a degree of donor secrecy that eclipses even the U.S. system.
These parallels are startling: just as in America, moneyed interests in India found a way to bypass disclosure. In both countries, murky nonprofit networks and special instruments mean that the average voter has scant clue who is paying for campaign propaganda.
The result can be policies skewed toward backers rather than constituents, and a public increasingly suspicious that elections are for sale.
As of today, The Supreme Court of India has put a legal end to use of electoral bonds.
How Other Democracies Respond
By contrast, many democracies have imposed far tighter rules on campaign money. A Transparency International report notes that most OECD countries limit how much individuals and organizations may donate to parties or candidates, and explicitly ban corporate, union or foreign government contributions.
For example, Canada forbids any direct corporate or union donations and caps individual contributions at modest amounts (roughly equivalent to $850 USD per year), with donors above a small threshold fully disclosed. Germany prohibits corporate and trade union donations to parties altogether, relying instead on public funding; parties must disclose all donors above €1,000.
The United Kingdom similarly restricts foreign contributions and requires full reporting of major donors. Even within the EU, transnational parties that accept EU funds must publicly list donors contributing over €5,000. In these systems, “dark money” is vastly more constrained, and electoral commissions are usually empowered to audit and enforce the laws.
Global research suggests that such controls can narrow the influence of wealthy interests and improve accountability. One Transparency International review finds evidence that donation caps reduce quid-pro-quo risk and help challengers compete more fairly.
Of course, limits alone are not a panacea – enforcement and transparency are key – but most other democracies still err on the side of strict disclosure and lower caps. The U.S. is a notable outlier, having loosened virtually all post-Watergate guardrails since 2010. As public cynicism mounts, many analysts argue that meaningful reform (from requiring ID reporting for all political ads to restructuring the FEC) will be needed to align America with the norms of its peers.
The Human and Democratic Toll
The eye-popping figures from 2022 in this series of investigative reports about dark money news underscore a simple truth: where money flows, so goes influence. Tens of millions in secret donations did more than just boost ad buys – they altered the narrative and priorities of the campaigns themselves. Campaign veterans warn that when candidates feel beholden to undisclosed patrons, policy debates suffer. Special interests, not ordinary citizens, gain the ear of officeholders.
In the spring of 2023, Senator Sheldon Whitehouse and Representative Jamie Raskin summed it up bluntly: “dark money flooding elections is a cancer on democracy” demanding systemic cures.
Public confidence is already strained. A survey by the Pew Research Center showed that a majority of Americans blame big money for unfairness in politics and want stricter limits. Critics worry that unchecked dark money will further depress turnout, as voters feel their votes are outweighed by billionaire checkbooks.
The 2022 midterm experience – with its deluge of secretly-funded ads targeting both liberal and conservative voters in swing states – may only have amplified that disillusionment.
For now, there is no quick fix. Any attempt to impose new limits or reporting requirements faces political and legal hurdles. Federal lawmakers have proposed various bills to revamp finance rules and empower the FEC, but none have passed. The next elections threaten to be even more expensive: outside groups are already roaring to spend in 2024, with projections that dark money could surpass even the 2022 binge.
Absent reforms, the corrosive incentives remain. As public interest advocates warn, when electoral outcomes are financed by the ultra-wealthy out of sight, the integrity of the democratic process itself comes under threat. After 2022, it is clear that dark money’s grip is strong – and that better transparency and accountability will be needed to loosen.
