Both cited sources are reachable and support the FULL rating that the Senate's legislative filibuster (60-vote threshold) was preserved and that McConnell acted consistently with his pledge. NOTUS documents McConnell flatly rejecting the nuclear option to eliminate the filibuster with the verbatim quote "We're not going to do that," and states the filibuster was not eliminated. PolitiFact (Nov 4, 2025) documents that the Senate was "not any closer to 'nuking' the legislative filibuster than we have been for decades" despite Trump's shutdown-era pressure, because Senate Republicans refused to change the rule. FULL is correct, not CHAMPIONED: PolitiFact makes clear the current institutional defense was led by Majority Leader John Thune (McConnell stepped down as GOP leader in Jan 2025 and now appears mainly in historical context), so McConnell was a vocal opponent of elimination rather than the person leading/authoring the preservation effort. His action exceeds a single vote (a repeated, on-record public refusal) but does not reach documented leadership, so the rating correctly stops at FULL. Confidence is tempered because the rules change never reached a formal roll-call (it lacked the votes, so McConnell's action is public refusal rather than a recorded vote) and the promise horizon extends beyond the late-2025 record.
