What the money says

Plain language · cited

Raised $9,533,641 in the 2022 cycle. FEC ↗ Placed at approximately the 39th percentile among other U.S. Senate members this cycle.

37.4% of individual money came from small-dollar donors under $200. PACs supplied 29.1% of contributions. FEC ↗

Direct contributions — individuals, PACs, and party — make up 83.5% of receipts (excluding self-funding and loans); the rest is transfers from other committees and other receipts, also disclosed. FEC ↗

Auto-generated from the data above

Funding is spread across individual and committee sources, with no single category standing out from the rest of the U.S. Senate.

Funding profile

Unweighted · never a blended score

Small-donor (grassroots) share37.4%

From the unitemized (sub-$200) total, which reconciles exactly against FEC's individual-contribution figure. Small gifts that ActBlue/WinRed itemize aren't counted here — see the size-based measure below.

Small-dollar by transaction size38.5%

Share of itemized + unitemized contributions received in individual transactions under $200 (FEC schedule_a/by_size), counting each gift by its own amount — so it captures small repeat donors the unitemized field hides. Its denominator is raw itemized receipts, so it reads conservatively.

PAC share of contributions29.1%

Committee & JFC transfer share14.5%

Share of receipts (excluding self-funding and loans) that arrived as transfers from joint-fundraising and other authorized committees rather than direct contributions — reported in the sending committees’ filings, never undisclosed “dark” money. This bar is the transfer component only, not the whole non-direct remainder — a determined 0% means no transfer receipts (other complement receipts such as offsets may still exist); “—” means no external receipts to decompose.

In-state contributor share34.7%

Share of itemized individual dollars from in-state donors — unitemized (<$200) contributions have no state breakdown.

Top-20 donor concentration8.1%

Share from the 20 largest individual donors this 2-year period, by exact name — a neutral concentration measure, approximate (recurring small-dollar donors may be undercounted), not a score.

Funding mix & position over time

Across every election cycle on record

Small-dollar share up from 0% (1984) to 45.2% (2026) A cycle with too little reported money to trust any ratio is left out entirely; a cycle where one specific figure can't be computed (e.g. an all-itemizing committee has no small-dollar figure to read) is left out of just that line.
