Campaign finance
Federal Election Commission filings for the 2026 two-year cycle. Candidates appear in the order they are listed on this page. They are not ranked by money, and these measures are never combined into a single score.
Every candidate below reports through Aug 12, 2026.
| Candidate | Total receipts | Cash on hand | Direct PAC receipts | Outside spending supporting | Outside spending opposing |
|---|---|---|---|---|---|
| Katherine M. Clark Democratic incumbent | $4,503,671 | $2,047,792 | $1,838,507 | $0 | $0 |
Bars are not shown. Only Katherine M. Clark has complete FEC data for the 2026 cycle, so there is no same-scale comparison to draw. Every reported amount is in the table above. Each column is one candidate and each figure is that candidate's own money, taken over that candidate's own itemized total. Nothing here is added across candidates, and the two groupings below are never added to each other: the first is who the FEC says runs the giving committee, which covers every dollar, and the second is what interest a source says that committee advances, which is a claim MyRepTracker makes and covers only part of the money.Where each campaign's committee money came from

Last-minute contributions reported before an election
Within 48 hours of receiving a contribution or loan of $1,000 or more in the days just before an election, a campaign must notify the FEC. These notices are provisional: the same money appears again in the regular report covering those days, so it is not added to the amounts above and is not compared as a measure. Candidates file them only while their own election is close, so an absence here says nothing about a campaign's fundraising.
| Candidate | Reported on notices | Notices | Covers | State |
|---|---|---|---|---|
| Katherine M. Clark Democratic | $54,500 | 8 | Aug 18 to Aug 28, 2026 | $54,500 still provisional |
Direct contributions are money the campaign received. Independent expenditures are spending by other organizations that is not coordinated with any campaign, and are never added to a candidate's receipts. Source: Federal Election Commission ↗.
