Official Roll-Call Threshold Audit

Effective Present Senators: 98

Majority Effective Votes: 50

Minority Effective Votes: 48

Net Floor Margin: 2

Simple Majority (Floor Vote): Passed (50-48)

60-Vote Cloture Hurdle: Failed (98 Present, 60 Required)

Procedural Rule Impact: Cloture under Senate Rule XXII strictly demands 60 affirmative votes regardless of general member absence (unless a measure amends Senate rules, which requires two-thirds of those present and voting). Simple majority confirmations and budget reconciliations hinge strictly on members present and voting, making single-seat returns like McConnell’s mathematically decisive.

Model Calculation Basis

Under Article I, Section 5 of the U.S. Constitution, a majority of the Senate (51 members) constitutes a quorum to do business. Passage for ordinary motions requires a simple majority of those present and voting. Cloture on legislation under Rule XXII requires three-fifths of all Senators duly chosen and sworn (60 votes).
