The gap: on the floor this would pass — 52% by the member-vote simulation — but the floor is the hard part: 2% to ever get the vote. That gap, not the whip count, is the story.

If it reaches the floor

60 (cloture)

Projected 67 yea of 100 voting; 90% interval 44–96 (quartiles 53–84). Intervals are backtest-verified to cover ~90%.

Filibusterable: the realistic Senate line is 60 votes — P(≥60) = 52% (simple-majority P = 93%).

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%	69 [42–96]	93%
passage	95%	67 [45–96]	93%
