Money in politics
Super PACs let wealthy donors, unions, and corporations influence elections at a scale individual contribution limits were designed to prevent.
In plain English
When unlimited money fuels campaign ads.
A super PAC can spend as much as it wants on ads for or against a candidate — it just can't hand money to the campaign or plan strategy with it.
Simple example
Following the 2010 Citizens United and SpeechNow decisions, super PACs spent billions across the 2012-2024 election cycles.
Why it matters
What the term actually changes.
Accountability
Because they are formally independent, candidates can benefit from attack ads while keeping distance from their content.
How it works
The mechanics, in practice.
Unlimited raising
Individuals, corporations, and unions can give any amount — unlike the strict caps on donations to campaigns.
Independent spending
The money goes to ads, mailers, and canvassing run separately from the candidate's own operation.
The no-coordination line
Coordinating strategy with a campaign is illegal, though critics argue the line is routinely blurred in practice.
