Where the money came from
| Source | Amount | Share |
|---|---|---|
| Individual donors Donations from individual people (itemized gifts plus small unitemized ones). | $15,299,979 | 68% |
| PACs and other committees Contributions from political action committees and other non-party committees. | $1,593,454 | 7% |
| Party committees Contributions from political party committees. | $62,000 | 0% |
| Transfers from the candidate's other committees Money moved between the candidate's own authorized committees. | $5,371,811 | 24% |
| Other reported receipts Computed: total receipts minus the lines above. Includes anything the FEC summary does not itemize here, such as refunds adjustments, interest or event income. | $137,974 | 1% |
Individual donors include small gifts the campaign was not required to itemize. These categories are kept apart on purpose: a gift from a person is not a gift from a company, and a PAC is not a person.

Largest individual contributions
Each line is one itemized gift as reported, in the donor's own words (employer and occupation are what the donor told the campaign; an employer is not the donor). Gifts are never added together by name. Information about individual contributors is public record, but federal law forbids using it to solicit contributions or for any commercial purpose (52 U.S.C. § 30111(a)(4)). People who share a name are never combined here, and no street addresses are shown.

Figures are copied from Federal Election Commission (FEC) filings and are only as complete and current as those filings. Reports are filed on a schedule, so recent money may not appear yet. FloorHoller does not alter official amounts. A campaign contribution is a lawful, public, reported act. Nothing on this page suggests that any contribution, or any amount, is improper. How this works
