All three cited sources are reachable and each quoted string appears verbatim. (1) The Louisiana Department of Revenue page confirms 'The constitutional amendment maintains the current state sales tax exemptions for groceries, residential utilities, and prescription drugs' — establishing that the STATE exemption pre-existed and was only to be maintained, not newly eliminated. (2) The National Law Review confirms voters 'rejected that amendment by over 60% of the ballots cast,' documenting the failure of the ballot measure (it discusses the amendment broadly and does not itself detail the prescription-drug clause, but it squarely establishes the rejection outcome). (3) The Office of Governor Landry page confirms verbatim 'Let's agree to totally eliminate the sales tax on prescription drugs once and for all!', documenting that Landry actively proposed/championed the elimination. Collectively the sources document a genuine, championed effort that failed within the ordinary legislative/ballot process: the state exemption was merely kept, the broader elimination (local/parish tax + constitutional protection) did not happen, and the March 2025 amendment was defeated. ATTEMPTED accurately reflects effort-without-success and does not overstate leadership or achievement. The moderate confidence is warranted because the promise's literal wording ('state tax') was already at zero and stayed there, while the elimination Landry actually pursued was not achieved. The rating is upheld.
