Candidate adjustmentIncluded in sealed margin
The state’s partisan baseline is R+18.0 (Cook PVI, a third party’s number, not ours). This forecast has the office running 31.5 points more Democratic than its state. The gap is the office-and-candidate effect: what this race does that its state alone does not explain.
How this margin was built is not available for this surface yet. The statewide-downballot and state-legislative published artifacts carry the final center but not an end-to-end contribution ledger. The site will not invent or recompute one in the client.
TWIN means Typology-Weighted Inference from Neighbors, Call the Map’s comparable-unit matching engine for any kind of race. It borrows poll residuals only—never centers, terrain, or outcomes. Similarity is demographic and behavioural, not geographic, and each contribution decays with similarity distance. Borrowed evidence always has lower precision than a race’s own polling.
No TWIN signal is published. No published TWIN evidence row exists for this race or surface.
