All three cited sources are reachable and support the CHAMPIONED rating with demonstrated leadership. Source 1 (Governor's office, PRIMARY) contains the verbatim quote "We ensured citizens are paying less money to government by lowering income taxes, nearly tripling the standard deduction, and FULLY eliminating income taxes for the working poor," and confirms Landry led the dedicated tax-reform special session and achieved his stated goals. Source 3 (Grant Thornton) verbatim confirms "On Dec. 4, 2024, Louisiana Gov. Jeff Landry approved a package of extensive tax reform legislation" and "H.B. 10 enacts a flat individual income tax rate of 3% for taxable periods beginning in 2025" — i.e., he signed the overhaul into law. Source 2 (Governor's office) confirms the ~$500 typical-family and ~$261 average-individual savings, the standard deduction tripled to $12,500, no income tax on the first $25,000, and the flat 3 percent rate. This is executive leadership — calling/leading a special session and enacting the agenda — not a mere vote or expression of support, so CHAMPIONED is warranted over FULL/PARTIAL. The enacted law delivers every element of the promise: it overhauled the system, lowered income taxes, and moved to eliminate income tax for the working poor. Confidence is 0.90 rather than 0.95 because Source 2's cited quote is a slight composite (the page says "second lowest in the nation," not the rating's "second lowest nationally, lowest in the South") and the "working poor" elimination is achieved via a deduction threshold rather than a literal statutory carve-out — but neither issue is a fabrication and both are minor.
