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.

Where each campaign's committee money came from
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.

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 |
|---|---|---|---|---|
| Byron Sigcho Lopez Independent | $13,000 | 3 | Mar 1 to Mar 15, 2026 | Covered by regular reports |
| Patty Garcia Democratic | $42,000 | 5 | Feb 28 to Mar 14, 2026 | Covered by regular reports |
Candidates not compared
These candidates are left out of the comparison rather than shown as zero, because a missing or partial record is not the same as no money.
- Edward Hershey (Working Class): No FEC data is stored for cycle 2026.
- Lupe Castillo (Republican): No FEC data is stored for cycle 2026.
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 ↗.
