The gap: on the floor this would pass — 69% by the member-vote simulation — but the floor is the hard part: 17% to ever get the vote. That gap, not the whip count, is the story.

If it reaches the floor

majority

60 (cloture)

Projected 71 yea of 100 voting; 90% interval 43–97 (quartiles 57–87). Intervals are backtest-verified to cover ~90%.

Filibusterable: the realistic Senate line is 60 votes — P(≥60) = 69% (simple-majority P = 92%).

By floor procedure

No vote is scheduled, so the headline marginalizes over how the Senate would take it up; the branches:

Procedure	Likelihood	Projected yea	Passes
conference	5%	74 [48–98]	94%
passage	95%	71 [42–97]	92%
