Senator Catherine Cortez Masto (D-NV), in office since 2017, presents a relatively clean self-dealing profile. Public disclosures and trackers show she holds her assets in mutual funds, retirement accounts, and bank holdings rather than trading individual stocks, eliminating STOCK Act timing/committee-overlap concerns; FactCheck.org found she was already a millionaire before office and her net worth grew only modestly (not "doubling" as claimed in attack ads). She is a substantial recipient of finance, securities, and legal-industry money while serving on the Banking and Finance Committees (correlation, not proof), and she has co-sponsored congressional stock-trading bans (the ETHICS Act). Her voting attendance is strong (1.2% missed, better than the Senate median), and no documented campaign personal-use scandal or family-lobbying pipeline tied to her Senate office surfaced in public records.

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-trading
25% weight
0
No individual-stock trading. Disclosures and Quiver Quantitative show holdings in mutual funds, a state pension (PERS), and bank accounts (e.g., up to $5M Town & Country Bank) rather than self-directed single-stock trades; Quiver tracks ~$0 in trackable publicly traded equities. She co-sponsors the ETHICS Act banning member stock trading. Per rubric, 0 when no individual-stock trading.
Modest growth from pre-existing wealth. FactCheck.org found she was a millionaire before her Senate tenure ($1.24M-$2.88M in 2015-16) and that her net worth grew to roughly $2.1M-$3.6M by 2021 - significantly less than the 'doubling' alleged in attack ads, and broadly consistent with salary plus passive market gains. No reported liabilities. Growth appears within normal market/salary bounds; pre-office wealth not scored.
Money → action alignmentcorrelation, not proof of any quid-pro-quo
20% weight
40
Correlation, not proof. She is a significant recipient of finance/securities/insurance and lawyer/lobbyist money while sitting on the Banking, Housing & Urban Affairs Committee (incl. Securities, Insurance & Investment subcommittee) and the Finance Committee - a structural overlap between donor industries and her jurisdiction. OpenSecrets tracks finance, real estate, and legal sectors among her top industries. No specific quid pro quo or anomalous vote documented; reflects routine donor-committee alignment common to senators with this portfolio.
No documented misuse of campaign or leadership-PAC funds for personal benefit found in public records. Her campaign committee files standard FEC reports; she has publicly advocated routing illegal contributions to the Treasury. No FEC enforcement action or credible reporting of personal-use spending identified. Per rubric, absence is not penalized.
Limited. Husband Paul Masto, a retired Secret Service agent, has provided security services to Nevada cannabis businesses (GreenMart, Silver Leaf Farms) - a private-sector role, not lobbying tied to her Senate office. A separate fundraising-party controversy dates to her tenure as state Attorney General, predating the Senate. No documented family lobbying contracts or staff-to-lobbyist pipeline tied to her current office surfaced.
Strong attendance. GovTrack records 46 of 3,787 roll-call votes missed (1.2%) from 2017 to mid-2026, better than the Senate median (~2.8%); she ranked among the most present senators in 2022. No evidence that fundraising or paid speeches displaced legislative duties. Low score reflects diligent attendance.
