Citizens United & Dark Money
The Citizens United ruling opened the floodgates to unlimited, often anonymous corporate and billionaire spending in elections. Dark money nonprofits now spend hundreds of millions per cycle with zero donor disclosure.
In 2010, the Supreme Court ruled that corporations are people and money is speech. In the fourteen years since, over $1 billion in anonymous 'dark money' has flowed into American elections — and that's only what we can trace.
Overview
Citizens United v. FEC (2010) was a 5-4 Supreme Court decision holding that the First Amendment prohibits the government from restricting political expenditures by corporations, associations, or labor unions. The ruling built on an earlier decision — Buckley v. Valeo (1976) — that established money as a form of protected speech.
The practical effect was the creation of Super PACs, which can raise and spend unlimited amounts from any source, as long as they don't "coordinate" with campaigns — a prohibition that has been widely documented as toothless. The 2012 election was the first under the new rules; the 2020 election saw $14 billion in total spending, the most expensive in history.
More consequential than Super PACs is the dark money system built around 501(c)(4) "social welfare" nonprofits. These organizations can spend unlimited amounts on political advertising without disclosing their donors. The Koch network, the Sixteen Thirty Fund (linked to progressive groups), and similar organizations have spent hundreds of millions per election cycle with complete anonymity.
The Court's subsequent ruling in McCutcheon v. FEC (2014) eliminated aggregate contribution limits, allowing a single donor to give the maximum amount to every federal candidate. The result: a small number of ultra-wealthy donors now exercise disproportionate influence over which candidates can viably run for office.

Charles Koch
Built the most sophisticated dark money infrastructure in American political history, spending hundreds of millions per cycle through a network of nonprofits.

Wrote the Citizens United majority opinion, asserting that independent expenditures 'do not give rise to corruption or the appearance of corruption.'
Mitch McConnell
Has argued against campaign finance limits throughout his career. Called Citizens United 'the most important First Amendment ruling in decades.'
How Dark Money Actually Works
A 501(c)(4) organization can spend up to 49% of its budget on political activity without registering as a political committee and without disclosing donors. This creates a simple money-laundering structure for political funds: a donor gives to the nonprofit, the nonprofit funds political ads, and no one ever knows who paid for them.
The Sixteen Thirty Fund, a progressive dark money hub, and its conservative counterpart DonorsTrust have each channeled hundreds of millions of dollars from anonymous donors to political causes. Both sides use identical structures — the difference is largely in the causes they fund.
Senate Majority PAC, House Majority PAC, and their Republican equivalents are technically "super PACs" that must disclose donors — but they frequently receive funds from dark money nonprofits, making the true source of the money untraceble. The FEC's deadlocked 3-3 partisan structure has prevented meaningful enforcement.
The Coordination Fiction
The legal distinction between "independent" expenditures and coordinated campaign contributions rests on a fiction: that outside spending groups don't coordinate with campaigns. In practice, coordination happens openly.
Former campaign staffers run Super PACs for their old bosses. Campaigns post detailed "voter files" and ad strategies online — publicly available, so technically not a private communication with the Super PAC. Candidates hold fundraisers for Super PACs supporting them. The FEC has consistently declined to enforce coordination rules, with commissioners deadlocked on virtually every enforcement case.
The result is a system where billionaires can effectively fund campaigns with no legal limits, subject only to a bookkeeping fiction.
The Bottom Line
Citizens United didn't create political corruption — it legalized and supercharged it. The system now functions as designed: unlimited anonymous money flows to candidates who protect the donors' interests, and the public has no legal right to know who is buying their elections.
