How is presidential campaigning financed?
Presidential campaigns are funded through a complex mix of individual contributions (subject to federal limits), party fundraising, Political Action Committees (PACs), and independent expenditures by Super PACs. The regulatory framework has evolved significantly since the Citizens United decision in 2010.
- Individual contribution limit: $3,500 per election (2025-26 cycle) to a candidate committee
- Super PACs: Can raise unlimited funds but cannot coordinate with campaigns
- Disclosure required: Most contributions must be reported to the FEC
- Total spending: Presidential campaigns can cost over $1 billion per candidate
Types of campaign money
| Type | Limit | Rules |
|---|---|---|
| Hard money (direct to candidate) | $3,500 per person per election (primary and general count separately) | Most regulated; must be disclosed |
| Party contributions | Various limits; parties can make coordinated and independent expenditures | Disclosed; some coordination permitted |
| PACs | $5,000 per candidate per election | Must register; contributions disclosed |
| Super PACs | Unlimited contributions | Cannot coordinate with candidates; must disclose donors |
| 501(c)(4) groups | Unlimited | "Dark money"—donor disclosure not required |
Citizens United and its impact
The Supreme Court's 2010 decision in Citizens United v. FEC held that corporations and unions could make unlimited independent expenditures on elections as a form of protected speech. This led to the creation of Super PACs, which can raise and spend unlimited amounts but cannot legally coordinate with candidates or parties.
While candidate committees face strict contribution limits and disclosure requirements, the independent expenditure system means vast sums flow through entities with varying transparency requirements.
Public financing
A voluntary public financing system exists for presidential campaigns, funded by the $3 checkoff on tax returns. However, major-party candidates have largely stopped using it because accepting public funds imposes spending limits, and candidates can typically raise more privately. No major-party nominee has accepted general election public funding since 2008.
The scale of spending
Total spending on presidential elections (including primaries, conventions, and independent expenditures) has grown dramatically. The 2020 presidential race saw combined spending exceeding $14 billion across all federal races, with the presidential contest alone accounting for billions.

The simulation abstracts campaign finance into a "war chest" mechanic. You allocate funds to different activities, and strategic fundraising decisions affect your budget. The game models the importance of money while simplifying the regulatory complexity.
