Independently verified all three cited sources are real, live, and support the outcome. Dunleavy personally led this effort: on Jan 30, 2019 he unveiled and sponsored a package of constitutional amendments including a 'spending limit and savings rule' (SJR 6), reintroduced the spending-cap amendment in 2021, pressed it in special sessions, and was still driving stricter spending caps in his 2026 fiscal plan (reducing allowable growth from 5% to 1%). However, an Alaska constitutional amendment requires a two-thirds vote in both chambers plus voter ratification; SJR 6 died in committee (last action S FIN, April 2019) and the amendment never cleared the legislature or reached the ballot, so it was never enacted. He actively led/sponsored/drove the effort well beyond a single vote (rules out ATTEMPTED) but did not achieve enactment (rules out FULL/PARTIAL) — matching CHAMPIONED. The label is nonpartisan-fair: a governor of either party who authored, championed, and repeatedly reintroduced a signature constitutional amendment would earn the same. Note: the promise concerns a CONSTITUTIONAL limit; the 2026 5%-to-1% proposal is a statutory limit and still only a proposal, so it does not elevate this to PARTIAL enactment of the constitutional promise.
