How Super PACs Work

Understand what Super PACs can and cannot do, and how independent spending affects elections.

Last updated: February 22, 2026.

A Super PAC is a political committee that can raise and spend unlimited amounts on independent political communications.

Key Rules

  • Super PACs cannot donate directly to federal candidates.
  • They may support or oppose candidates through independent expenditures.
  • They must file disclosure reports with the FEC.

Practical Impact

  • Super PAC spending can be significant in close races.
  • Spending may surge late in a cycle, changing media balance quickly.
  • Voters often use filing data to understand which groups are active in a race.
  • Compare finance pressure signals on profile pages.
  • Track outside spending on the fundraising analytics page.
