Projected turnout: 365,709 votes · model estimate, not counted votes.
Displayed shares include the model's Other-vote allowance and therefore add to 100%. Interval endpoints are the model's 10th and 90th percentiles, not a polling margin of error.
SURE — · not yet rateable
How reliable is the evidence behind this race's number — not who wins. A safe seat with no polls can score low while its forecast is easy.
No public poll of this race has been fielded yet. SURE rates poll evidence, so it has nothing to rate here — this is an absence of evidence, not a judgement that the evidence is weak.
Limited evidence: zero polls. The fitted race-error distribution widens automatically; no manual score penalty or race override is applied.

SURE v3 — historically calibrated evidence-conditioned uncertainty · generated 2026-07-27. SURE rates the EVIDENCE behind a race's number, not the outcome: a safe seat with no polls can score low while its forecast is easy. Never a second win probability. It changes only idiosyncratic uncertainty, never the center. Senate marginal intervals are historically calibrated under the stated 0-120 day assumptions; House/Governor conditioning is provisional and widen-only until chamber-specific history passes the same gates.

TWIN neighbours
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.

Money in this race
Who does this money help? These are independent expenditures — spending by groups that are not the campaigns and may not coordinate with them. Each dollar is reported either supporting one candidate or opposing another, and both can help the same person, so the table below nets them out per candidate. It lists everyone with reported activity in this cycle's FEC filings — which can include primary candidates who are no longer on the ballot.
