About this series
This comparable series begins on September 9, 2026, when the model version changed to CTMM 2.2. Earlier readings remain in the archive and are not joined as voter movement; faded points before September 9, 2026 are reconstructions, not forecasts issued on those days.
Faded: CTMM 2.2 reconstructed history: computed after the fact with each date's available polls and environment, without expert ratings; not an issued forecast. Issued forecasts begin at the launch marker.
CTMM 2.2 readings for 2026-09-16, 2026-09-17, 2026-09-18 were computed after the fact with each day's available inputs: no edition was issued on those days. Not an issued forecast.
The polls
Poll average R+8.0A poll’s weight halves every 60 days and grows with its sample, up to one and a half times a 600-interview poll. Each pollster counts once, at its best release. A poll sponsored by a party or campaign counts at full weight, and its margin is moved 2 points against the party that paid for it. Margins are otherwise read as published.1 recorded poll · 1 in the poll average

All calculations & sources
This district's measured terrain −19.776 points
Call the Map's partisan lean on the CURRENT district lines, before any current-cycle evidence. Every pull below is measured from here — not from EVEN.
- Call the Map partisan lean, district geography bound to this forecast edition.
- Prior source: official_reaggregation_tx; district redrawn for 2026.
Fitted model, above the terrain shown +9.413 points
What the fitted model adds on top of the starting terrain above — incumbency, past results, campaign finance and the other fitted terms — measured from that terrain rather than from EVEN. It is a comparison with the starting point already shown, not a separate input. The source detail lists the variables the fit uses.
- Fitted baseline -10.362 minus starting point -19.776 = 9.413 points.
- One fitted structural total; this edition does not split it into partisan lean and incumbency.
- Fundamentals: −10.4 — the district's structural lean before this year's polling, money and candidate quality are added.
- This edition publishes that as one fitted total. It does not break it into a partisan-lean and an incumbency term, so this page does not invent that split.
- fundamentals core = 25-term dynamic formula (mass fit over the master feature matrix, held-out-cycle validated; see matrix/feature_dictionary.md + mass_fit_report.json)
- 40-term formula, held-out validated.
National environment +1.657 points
The contribution to this race’s margin, not the national polling margin itself. The race’s loading, reference level and polling blend determine how much of the national climate reaches its final forecast.
- Three-source blend, updated 2026-09-08: 51% generic-ballot aggregates (D+6.5) · 29% special-election overperformance (D+9.0 across 46 specials) · 19% approval-implied (D+8.6 from net approval -21.7).
- Latest polls — generic ballot 2026-09-08 (26 days old), approval 2026-09-10 (24 days old).
- Generic-ballot average D+6.5 · support factor 0.80 (the share of that channel's capacity the admitted polls carry) — separate inputs; their product is a capacity diagnostic, not a margin.
- Weights are the 55/25/20 capacities scaled by each channel's evidence and renormalized, so thin polling widens the interval instead of pulling the center toward zero — 19% of the weight is carried that way.
- Blended national environment: D+7.6.
- Applied at full strength to this chamber's races.
- The work: national environment × 1 chamber strength = +1.7 of this margin.
- Blended national environment: D+7.6 (updated 2026-09-08).
- Effective poll weight 81%; fundamentals share 19%, carried by the interval (×1.09) rather than by the center.
- The support factor is the share of the generic-ballot capacity the admitted polls carry; average × support is a capacity diagnostic, not a margin, and is not what the row above multiplies.
- Applied at full strength to this chamber: +1.7 of this margin.
This race’s polls +0.448 points
What this race’s own recent polling adds beyond its prior, after each poll is weighted for recency, sample size and pollster quality.
- Public Policy Polling (2026-09-19, n=560): R+6.0 · weight 0.81 in the poll average
- Poll average R+8.0, from 1 poll · 1 recorded poll. This is the forecast’s own average, the figure this page’s poll summary shows. The forecast gives the polls 63% of the weight against its structural prior for this race; the recorded polling contribution is +0.4 D. Eligible polls: latest poll: 2026-09-19 (15 days old).
The components this edition publishes for this race, in points. “Other factors” closes the sum to the two-party structural lean exactly. Here the structural lean IS the published margin, so the walk sums to the projection exactly; nothing is left over.
