All three cited sources are reachable and each supports the ATTEMPTED outcome with the quoted text appearing as claimed. (1) The Governor's Office press release (PRIMARY) confirms verbatim: "We're making sure that 45 percent of Nebraskans who have not been getting that credit will now receive a 20 percent property tax cut" and "This is not a one-and-done issue" — and shows the 40% goal was not achieved and "much more" remains. (2) Nebraska Public Media (REPUTABLE_SECONDARY) confirms LB34 "would cut property taxes overall by about 3%, and would not affect most people," and that Pillen proposed a much larger cut that "would cut property taxes in half"; the bracketed portions in the rating's quote are marked editorial insertions, not fabrication, and the core quoted phrases appear in the source. (3) Tax Foundation (REPUTABLE_SECONDARY) confirms "an additional $185 million to the existing property tax relief budget." The promise to cut property tax bills by 40% in 2024 was demonstrably not kept — Pillen pursued it forcefully (LB1/LB388 in regular session, then a special session he convened to force 40–50% relief), but the legislature passed a slimmed-down LB34 delivering only ~3% overall relief. ATTEMPTED accurately captures a genuine leadership-level effort that failed within normal process; it is not CHAMPIONED (outcome not delivered) and does not overstate the evidence — if anything it is the conservative reading, since the ~3% incidental result is too far below the 40% target and, by the governor's own framing, too marginal to count as PARTIAL delivery. Outcome is fully determinable, so not UNRATABLE.
