#101 of 193 scored

John Thune (R-SD), the Senate Majority Leader, presents a low-activity personal financial profile in the public record. Trackers of STOCK Act filings show only two disclosed individual-stock transactions in his household — a buy and a sell of Independence Realty Trust (IRT) in 2021-2022 — placing him among the least active congressional traders, with most remaining assets in mutual funds and real estate; estimated net worth figures are modest (roughly $230K-$1M ranges; OpenSecrets historically estimated low six figures). On money-and-influence, the clearest pattern (correlation, not proof) is that POET LLC, the world's largest biofuel producer, was the top donor to his 2024 joint fundraising committee at $538,100, and Thune is a long-standing, vocal champion of the Renewable Fuel Standard and ethanol policy; this reflects alignment between a home-state industry's giving and his legislative priorities, not evidence of any quid pro quo. Thune entered the Senate after a stint as a paid lobbyist for the Dakota, Minnesota & Eastern Railroad (2003-2004), and OpenSecrets/LegiStorm track a substantial staff-to-lobbyist pipeline from his office, though no family-member lobbying tied to his office was found in available sources. His voting attendance is excellent (about 0.8% missed votes over his career, well below the Senate median), undercutting any job-versus-fundraising concern. No FEC enforcement actions or watchdog findings of campaign-fund personal use were located in public reporting.

The stock-trading ban

Senate cloture on H.R. 7008, Sep 30, 2026
Yes
Cosponsored a ban bill
None

H.R. 7008 bans new stock purchases by members, spouses and dependents; it doesn't force sales of existing holdings. The Senate vote was on the version paired with the SAVE Act, which is why no Democrat voted yes. Full breakdown →

Disclosed stock trades

No periodic transaction reports on file since 2024. That's the norm: most members don't trade individual stocks, or hold them in blind trusts and diversified funds.

Amounts are the ranges members must report, not exact values. The STOCK Act requires a report within 45 days of a trade; "late" counts days past that deadline, measured to the filing date.

How the score breaks down

Stock self-tradinghousehold / spouse
25% weight
8
Only two disclosed individual-stock transactions ever (buy and sell of REIT Independence Realty Trust, IRT, in 2021-2022), total volume roughly $30K-$100K; among the least active congressional traders. Remaining holdings are mutual funds and real estate, not actively traded individual securities. No suspicious-timing or insider-trading allegations found.
Net-worth enrichment in office
15% weight
5
Estimated net worth is modest and ranges widely by source (OpenSecrets historically ~$310K for 2018; latest disclosure-range estimates ~$229K-$1.0M). No reliable public data shows net-worth growth beyond salary and market returns over tenure; wealth predating office is not scored. Wide reporting ranges limit confidence.
Money → action alignmentcorrelation, not proof of any quid-pro-quo
20% weight
45
Correlation, not proof: POET LLC, the world's largest biofuel producer, was the single largest donor to his 2024 joint fundraising committee ($538,100), and Thune is a long-standing, leading advocate for the Renewable Fuel Standard, E15/E85 expansion, and pro-ethanol legislation (e.g., the GREET Act, supported by POET). This reflects alignment between a home-state industry's giving and his legislative agenda; no quid pro quo is asserted.
Campaign-fund personal useno data
15% weight
—
No public reporting, FEC enforcement action, or watchdog finding of personal use of campaign or leadership-PAC funds was located. The only campaign-fund news found was that Thune's committee was a victim of external theft (not misuse by the campaign), which is not self-dealing. Absence is not penalized.
Revolving door & family
15% weight
38
Thune himself was a paid lobbyist (Dakota, Minnesota & Eastern Railroad, $220,000 in 2003-2004) before entering the Senate, then advanced that railroad's interests in office — a documented lobbyist-to-lawmaker transition. OpenSecrets/LegiStorm track a sizable staff-to-lobbyist pipeline from his office (LegiStorm: 24 people through the revolving door). No family-member lobbying tied to his office was found.
Skips the job to fundraise
10% weight
3
Thune has an excellent attendance record — about 0.8% of roll-call votes missed over his career (58 of 7,430 through June 2026), well below the Senate median of roughly 2.8%. There is no evidence of heavy missed votes coinciding with fundraising or paid speeches, so this self-dealing concern is minimal.
