About this series
Reconstructed with the current model Aug 1 – Sep 8 and Sep 16 – Sep 18; published readings Sep 9 – Oct 28. Each reconstructed day is the current model on that day’s own inputs, not a forecast published then. Corrections are dated in the changelog.
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+3.8A poll’s weight halves every 60 days and grows with its sample. Each pollster counts once, at its best release. Every poll counts at its published margin, sponsored or not.In governor races the forecast then counts a poll sponsored by a party or campaign at full weight and moves its margin 2 points against that party, which puts the average it reads at R+4.3. It then applies a fitted correction of 2.5 points toward Republicans for governor races, measured from past polling error, before blending it with its other evidence.7 recorded polls · 7 in the poll average

How the margin was built
Tap an input for its calculation and source.
Displayed values are rounded.
All calculations & sources
How this state voted, 2024 −16.120 points
The state's presidential margin in 2024 as a share of all votes cast, from our own county sums — the same measurement the model's statewide terrain center is built from. Every pull below is measured from here, not from EVEN, which is why a landslide seat's listed pulls are small numbers and still land where the forecast does.
- 2024 presidential result for this state, as a share of all votes cast, from Call the Map's own county sums.
- Same source as Act I's 2024-president reference mark, so the origin lands on it.
Fitted model, above the terrain shown +13.168 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 -2.952 minus starting point -16.120 = 13.168 points.
- Fitted intercept: -6.136 points.
- 2010 White population share used by the frozen historical fit: observed input 83.645. -0.503 × ((83.645 − 77.922) / 12.864) = -0.224 points.
- gov_midterm_wh: observed input -1.000. -0.987 × ((-1.000 − 0.336) / 0.739) = 1.785 points.
- 2024 presidential lean relative to the national result: observed input -14.911. 4.163 × ((-14.911 − -4.415) / 20.258) = -2.157 points.
- Previous governor election margin: observed input 2.210. 1.755 × ((2.210 − -3.131) / 19.227) = 0.488 points.
- gov_inc_running_signed: observed input 0.000. 2.531 × ((0.000 − -0.120) / 0.708) = 0.428 points.
- gov_inc_tenure_signed: observed input 0.000. 3.340 × ((0.000 − -0.143) / 0.902) = 0.529 points.
- The displayed arithmetic is rounded; the fitted terms use full precision. The intercept plus these five terms gives the non-ratings baseline.
- No source-verified current Gallup reading supports the former 40% / July 2026 claim. The current Gallup series ends in 2025; the Presidency Project identifies its 2026 observations as other pollsters. Use the unchanged fitted missing-value rule, not a replacement polling scale.
- Certified 2024 presidential baseline: state R+16.4, national R+1.5; subtracting the national margin gives relative lean −14.9. Source: FEC compilation of certified state results.
National environment +1.832 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.
- The national environment in this edition is D+8.4. This row is its contribution to the race’s prior, not a claim that the country is D+1.8.
- This step’s recorded contribution to the margin is +1.8.
- The elasticity is fitted on the pooled panel of contested governor races (2010–2024) with cycle-clustered standard errors; it is a measured response to the national environment, not a judgment floor.
This race’s polls −5.560 points
What this race’s own recent polling adds beyond its prior. The forecast weights each poll for recency and sample size and counts each pollster once; the weights listed here are those of the polls’ own average.
- Global Strategy Group (2026-10-21, n=600): ±0.0 · weight 0.61 in the poll average
- YouGov (2026-10-04, n=2,252): R+3.0 · weight 0.76 in the poll average
- The New York Times/Siena University (2026-09-30, n=605): R+4.1 · weight 0.48 in the poll average
- Emerson College (2026-09-16, n=750): R+7.3 · weight 0.46 in the poll average
- Global Strategy Group (2026-09-16, n=800): D+3.0 · weight 0.47 in the poll average
- co/efficient (2026-09-10, n=915): R+8.0 · weight 0.47 in the poll average
- … and 1 more below.
- Poll average R+3.8, from 7 polls · 7 recorded polls. This is the polls’ own average, each poll at its published margin, the figure this page’s poll summary shows. In governor races the forecast then counts a poll sponsored by a party or campaign at full weight and moves its margin 2 points against that party, which puts the average it reads at R+4.3. It then applies a fitted correction of 2.5 points toward Republicans for governor races, measured from past polling error, before blending it with its other evidence. The forecast gives the polls 98% of the weight against its structural prior for this race, which moves the margin 5.6 points toward Republicans from where it stood before the polls. Eligible polls: latest poll: 2026-10-21 (7 days old).
Historical error calibration −0.266 points
A prior-election residual correction, when an admitted model publishes one.
- The forecast’s calibration against past governor results. The recorded contribution is −0.3.
Votes for other candidates +0.224 points
Every step above is measured between the two major-party candidates alone, as if nobody else were on the ballot. The forecast sets 3.2% of the vote aside for other candidates and write-ins, so as a share of every vote cast the gap between the two is smaller by that much. This step is exactly that: the two-party margin times the share going to other candidates. It is the same arithmetic that turns the two-party margin into the two shares printed at the top of the page.
The components this edition publishes for this race, in points. “Other factors” closes the sum to the two-party structural lean exactly. The margin the page prints is a share of every vote cast, so the “Votes for other candidates” row carries the exact difference between the two-party lean and that margin; with it, the walk sums to the printed margin exactly.

Forecast as of October 28, 2026: Call the Map currently has Ty Masterson ahead of Cindy Holscher by R+6.8, with an 85 in 100 chance to win. This is an open seat. That result would flip the seat to Republicans. The current poll average is R+3.8; 7 public polls are recorded.
