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.

State of the race

Call the Map currently has Lankford ahead of Priest by R+32.9, with a 98 in 100 chance to win. The seat is currently held by a Republican. That result would keep the seat with Republicans. No current nominee-matched poll average is available, so the forecast is leaning on the non-polling evidence shown below.

Hern won the Republican nomination for the special election to Markwayne Mullin's former seat. Thomas leads Jim Priest into the August 25 Democratic runoff; James Lankford holds Oklahoma's other Senate seat.

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.

What would change this forecast

Computed from the model's own mechanics

This race is rated Solid R at R+25.7. Its win probability is separately 2%. These are the concrete, checkable events that would move that rating — computed by inverting the model's own poll blend and environment elasticity, not asserted. If one happens and the rating doesn't move, the model was wrong in public.

To Likely R

No single poll can re-rate this Likely R — the blend would need a poll at D+76, which no real poll shows.

The environment alone can't plausibly do it (it would have to reach D+33.1).

Poll and environment levers reverse the current blend (K=6) and environment sensitivity (0.6); rating lines use the same published point-margin bands as every race hero, map, and table. Win probability remains a separate quantity. Method on the methodology page. These are illustrations; they do not change the published forecast.

Candidate filings and outside spending

FEC receipts · independent expenditures

Candidate fundraising and independent expenditures answer different questions, so they are kept separate here. Receipts are money raised by the candidate committees; the air-war bars are outside groups spending for or against a nominee.

Outside spending over time

Independent expenditures reported to the FEC, by the month the money flew. Pre-primary bars can be intra-party spending, so the monthly shape is more informative than one undifferentiated total.

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.
