S. 4127 — Transportation Security Administration Pay Act of 2026

<1%becomes law moderate confidencepending: Senate on_calendar

Transportation Security Administration Pay Act — on the calendar, quiet for 80 days; <1% to reach the floor, <1% to become law.

<1%

reaches a floor vote

99%

passes if voted (stage model)

26%

survives downstream

<1%

becomes law

The gap: on the floor this would pass — 67% 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 69 yea of 100 voting; 90% interval 42–96 (quartiles 57–86). Intervals are backtest-verified to cover ~90%.

Filibusterable: the realistic Senate line is 60 votes — P(≥60) = 67% (simple-majority P = 90%).

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%	73 [47–97]	95%
passage	95%	69 [41–96]	90%
