Inferred, not stated. Cynthia M. Lummis has not necessarily stated these as goals. This is an AI-generated, nonpartisan reading of the patterns in their verified record — sponsored legislation, committee work, roll-call votes, and campaign-finance composition — and how those patterns compare to any declared positions and tracked promises. It describes what the record emphasizes, never imputes motive, and is run through an adversarial review pass that scrubs bias, loaded language, and any claim the evidence doesn’t support. It is not a quote, a claim they made, or a rating; every underlying item is sourced in the verified record below; and it never affects the Integrity Score.

Disclosure
A separate measure from the promise scorecard above. It tracks confirmed cases where this official has acted on or championed an issue that already existed when they ran, but which they did not disclose as a priority in their campaign. Each case meets a high evidence bar — three independent sources — and the score is shown alongside the Integrity Score, never merged into it. How this is measured.
No undisclosed priorities on record. This is not a clean-audit claim — it means none have been confirmed for this official.
