Adversarial re-check: all four cited sources were independently re-fetched and are REAL, live, and accurately quoted. (1) senate.gov roll call 119-1-100 confirms verbatim: vote on Cloture on the Motion to Proceed to S. 9 (Title IX sex-based-on-reproductive-biology bill), March 3, 2025, rejected 51-45 (60 needed), Blackburn (R-TN) Yea. (2) Her official Senate release dated January 14, 2025 confirms she INTRODUCED her own package: the Fair Play for Girls Act, a resolution calling on the NCAA to revoke its transgender student-athlete eligibility policy, and an American Girls in Sports Day resolution. (3) Her official release dated March 21, 2026 confirms she offered the Protection of Women and Girls in Sports Act with Sen. Tuberville as an amendment to the SAVE America Act, blocked by Senate Democrats. (4) Roll Call (Aug. 6, 2025) confirms her gubernatorial campaign launch; independently corroborated that the Aug. 6, 2026 primary and Nov. 3, 2026 general have not yet occurred and that Gov. Bill Lee is term-limited. Also independently confirmed Tennessee enacted its ban on transgender girls in girls' school sports in 2021 (signed by Lee, March 26, 2021), so the gubernatorial promise is status-quo maintenance. NEUTRALITY TEST APPLIED: the promise is conditioned on an office she does not yet hold, which argues for NO_OPPORTUNITY, and her legislative work is federal (Title IX/NCAA) rather than the Tennessee state instrument the promise names. But NO_OPPORTUNITY means 'no genuine opportunity to act yet,' and that is factually false here: she has repeatedly acted on this exact policy direction, authoring her own bills and floor amendments rather than casting a single supporting vote. Mirror-image test: a Democratic senator running for governor who promised 'as governor I will protect abortion access' and who sponsored the Women's Health Protection Act, voted cloture, and offered blocked floor amendments would likewise earn CHAMPIONED under this rubric, so the label is applied consistently and is not partisan leniency. FULL is clearly wrong (nothing enacted through her, she is not governor, and Tennessee's law predates and is independent of her). Confidence trimmed from 0.82 to 0.78 for two honest weaknesses: the March 21, 2026 amendment rests solely on her own office's press release (congress.gov and govtrack both returned 403 and search budget was exhausted, so it could not be independently corroborated), and the 'as governor' framing makes CHAMPIONED-vs-NO_OPPORTUNITY a genuine judgment call. The Jan. 14, 2025 introductions plus the independently verified March 3, 2025 roll call are sufficient on their own to establish leadership beyond a single vote, so the rating does not depend on the uncorroborated item.
