Start here
- Open your race. Every House and Senate race, with the outside money supporting and opposing each candidate, week by week, and the groups on each side. The races
- Follow a group. Every committee and organization has its own page: what it raised and spent, who gave to it, and who it’s linked to. Search
- Sign in for the paperwork. A free sign-in, with an email address or Google, opens the filings behind each figure. It’s a door, not a vault. Sign in
Three layers, one tap apart
- The bottom line. One sentence, one big number and one chart on every card. The answer, at a glance.
- The numbers. For each race, group and committee: supporting and opposing, candidate by candidate, week by week, the biggest givers, the polls and the result when it’s in.
- The record. The filings behind each figure, line by line, with a free sign-in.
How we work
- We read the public record so you don’t have to: the committees’ own filings, the platforms’ political ad libraries and official election results. Then we match the committees, nonprofits, companies and people behind them into one picture.
- Outside money is what a group spent on its own supporting or opposing a candidate. Which side is the group’s own word, and a total over many races is all candidates combined.
- New spending is counted as soon as it’s reported, and restated when the full report lands.
- Platforms report ads in their own ways, so we show them side by side and never add them together.
- A connection is drawn only when the filings themselves declare it, or when multiple independent records corroborate it. Online, that means shared online infrastructure in public web records. The rest is a magic trick.
- Every identity decision is recorded with its reasons, and every merge can be undone.
- Results appear as soon as they’re reported, and the final count replaces them when it lands.
