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 Ossoff ahead of Collins by D+6.0, with an 87 in 100 chance to win. The seat is currently held by a Democrat. That result would keep the seat with Democrats. The current 4-poll average is D+6.6.

Ossoff, the most-targeted D incumbent, drew Rep. Mike Collins after a divisive GOP runoff. Cook rates it Lean D.

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.

Borrowed term: ±0.000 points. This race has its own usable polling, so TWIN does not return borrowed evidence to it.

What would change this forecast

Computed from the model's own mechanics

This race is rated Likely D at D+7.0. Its win probability is separately 83%. 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 Solid D

A single fresh nonpartisan poll at D+28 or better for the Democrat would re-rate this Solid D.

The national environment moving from D+5.9 to D+9.9 would do it on its own.

To Lean D

A single fresh nonpartisan poll at R+19 or better for the Republican would re-rate this Lean D.

The national environment moving from D+5.9 to D+0.9 would do it on its own.

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.

Candidate fundraising · FEC receiptsJon Ossoff $77.3M vs Mike Collins $7.4M

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.
