Adversarial re-check: all three sources cited by the prior rater are REAL, live, and support the outcome, and I added five independent sources (including non-aligned Iowa outlets and a contemporaneous Politico report) that corroborate the record without relying on Ernst's own press shop. VERIFIED FACTS: (1) Ernst founded the Senate DOGE Caucus on 22 Nov 2024 -- contemporaneous with the promise -- as its chair, alongside House co-chairs Bean and Sessions and eight other Republican senators. (2) She did deliver the promised blueprint: the Ripon Forum interview quotes her saying she met Musk and Ramaswamy at Mar-a-Lago in November 2024 and 'presented them with a blueprint of about $2 trillion of savings'; the House Budget Committee circulated the same ~$2 trillion options list. (3) She has driven the effort personally rather than casting a single supporting vote: she authored the Stop Secret Spending Act (S.872), which the Senate passed unanimously on 12 June 2026 -- independently confirmed by Iowa radio reporting on 15 June 2026 -- and on 16 July 2026 introduced the Protecting American Taxpayers Act (S.4378), a 16-part anti-fraud package projected to save $240 billion and claw back over $65 billion in unspent COVID funds, which Radio Iowa independently reports drew 21 additional Republican co-sponsors and was developed through the DOGE Caucus. She also uncovered $77 billion in undisclosed DoD R&D spending and runs recurring waste reports. COUNTER-EVIDENCE WEIGHED: the headline $2 trillion was never realized. Ernst's own high-water claim was 'more than $15 billion worth of savings' as of August 2025 (Daily Caller News Foundation) -- under one percent of the blueprint -- and as late as October 2025 she was still describing the $2 trillion as potential savings contingent on the administration acting. That shortfall is why this is not FULL. NEUTRALITY TEST: applying the same standard to a member of either party, founding and chairing the effort, delivering the specific promised artifact, authoring a bill that cleared the Senate unanimously, and leading a 22-senator legislative package is leadership well beyond a supporting vote, so PARTIAL would understate it; but with the promised dollar figure unrealized and the waste not 'ended', FULL would overstate it. CHAMPIONED (+0.75) is the correct band. TWO MINOR CORRECTIONS to the prior rating, neither changing the outcome: the quote 'You can't cut waste you can't see' does appear on the cited Ernst press release but is spoken by Senator Lankford, not Ernst -- replaced here with Ernst's own words from the same page; and the prior rationale's claim that the largest enacted item was a '$9 billion rescissions package targeting USAID and the Corporation for Public Broadcasting' could not be substantiated in this pass and has been dropped rather than repeated as fact.
