About this field

DeSantis is term-limited. Jolly and Donalds are current leaders in contested August 18 primaries; neither nomination is settled.

Forecast share averages the simulated vote. Win chance counts how often a candidate wins. A wider range of outcomes can give a candidate a higher win chance despite a lower average share.

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.

All calculations & sources

How this state voted, 2024 −13.100 points

The state's two-party presidential margin in 2024, 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, two-party, 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 +7.781 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 -5.319 minus starting point -13.100 = 7.781 points.
  • Fitted intercept: -6.136 points.
  • 2010 White population share used by the frozen historical fit: observed input 75.083. -0.503 × ((75.083 − 77.922) / 12.864) = 0.111 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 -11.722. 4.163 × ((-11.722 − -4.415) / 20.258) = -1.502 points.
  • Previous governor election margin: observed input -19.400. 1.755 × ((-19.400 − -3.131) / 19.227) = -1.485 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+13.2, national R+1.5; subtracting the national margin gives relative lean −11.7. Source: FEC compilation of certified state results.

National environment +1.079 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+7.6. This row is its contribution to the race’s prior, not a claim that the country is D+1.1.
  • The environment enters once, through the fitted governor elasticity: 0.4216 × (7.600 − 1.882, the environment the governor priors themselves imply) = +2.4; the producer rounds the contribution to +2.4.
  • Polls receive 69.8% of the blend. They attenuate this contribution to +0.7 in the final center; the offset is included in the polling row.
  • 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 −0.787 points

What this race’s own recent polling adds beyond its prior, after each poll is weighted for recency, sample size and pollster quality.

  • 20 poll(s) / 14 pollster(s)
  • The admitted polling average is R+1.7, after pollster, sample and recency adjustments.
  • Polling contribution = 69.8% × (-1.676 − prior -10.160) = −0.8 points after component rounding.
  • The prior includes national environment and expert ratings. The blend is R+4.2 before the separately disclosed candidate and formula adjustments.

Historical error calibration −0.011 points

A prior-election residual correction, when an admitted model publishes one.

  • No separate historical residual correction is published in this governor edition.

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.
