Department of Defense Appropriations Act — must-pass class. On the calendar, quiet for 310 days; the <1% reflects timing risk, not whether something passes.

The gap: on the floor this would pass — 48% by the member-vote simulation — but the floor is the hard part: <1% to ever get the vote. That gap, not the whip count, is the story.

If it reaches the floor

majority

60 (cloture)

Projected 65 yea of 100 voting; 90% interval 42–94 (quartiles 52–82). Intervals are backtest-verified to cover ~90%.

Filibusterable: the realistic Senate line is 60 votes — P(≥60) = 48% (simple-majority P = 91%).

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%	68 [50–96]	96%
passage	95%	65 [41–94]	91%
