Mast's fundraising profile shows moderate PAC reliance at 42 percent of total contributions, with the remaining 58 percent drawn from individual donors; separately, $2.5 million in party and leadership money accounts for a significant portion of his overall $9.6 million raised. Industry-tied contributions span transportation, labor unions, securities and investment, defense and aerospace, and real estate, with no single sector dominating his economic donor base. Individual donors employed in securities and investment, real estate, and legal services represent the clearest sectoral pattern in his personal donor network.

How to read this: percentages are shares of the 45% of contributions we can trace to an industry (via PAC names and donor employers). Most political money comes from small online donors who don't list an employer, so it can't be traced — that portion isn't shown here.

HOW WE CALCULATE THIS

Donor Mix Donut

Shows PAC contributions and employer-attributed individual donations grouped by industry — as a share of classified giving only. Contributions that could not be matched to an industry are excluded from the donut but included in the dollar totals above. Advocacy/ideological PACs are excluded from industry breakdown.

What are aggregators?

WinRed, ActBlue, and similar platforms bundle contributions from many individual donors before passing them to campaigns. Because these don't represent a single entity's interests, they are excluded from the Donor Mix and Top Sources views — but they are counted in total fundraising figures.

Data sources

FEC Schedule A & bulk PAC filings · 2022–2026 cycles · Lobbying Disclosure Act (LDA) filings · 2017–present · Congress.gov / House Clerk voting records.

Important disclaimer

All data is sourced from public records. Analysis reflects statistical patterns only — it does not imply corruption, intent, or quid pro quo. Donor relationships show financial alignment, not control. Capitol Trail makes no claims about the motivations or character of any individual or organization.

WHAT YOU'RE LOOKING AT

Lobbying is when companies, unions, and trade associations pay firms to influence laws and regulations — and the law requires them to disclose it. Every quarter, registrants file a report with Congress detailing who hired them, how much they spent, and which issues they pushed.

This page filters those filings to the industries that also fund this member's campaign. If commercial banks gave 30% of this member's donations and also filed 5,000 lobbying reports on bank-related issues last year, that's a financial pattern worth knowing about. It does not mean the member is corrupt — it means the industries paying to elect them are also paying to influence the laws they vote on.

SOURCES & CAVEATS

Data: LDA (Lobbying Disclosure Act) quarterly filings · 2017–present

Amounts are self-reported by registrants. Issue codes are mapped from the LDA's 80+ general issue codes to our 19-industry taxonomy.

An industry showing up here means it both (a) funds this member's campaign and (b) lobbies Congress on issues affecting it. That overlap is a factual pattern, not proof of any quid-pro-quo.
