Historical accuracy is measured against certified results. Current-cycle records come from the canonical, deduplicated archive and do not by themselves change the sealed forecast.
13 eligible historical polls across 7 represented cycles passed the published history identity checks. Historical bias is descriptive and is kept separate from sponsor or client affiliation.
Archive source date 2026-09-09 · bundled copy. Archive records may be newer than the sealed forecast; inclusion here does not mean the forecast uses them.

1 further row is held in this pollster’s history shard as within-party or nonpartisan contests (Prim). Those carry no D/R orientation, so they are excluded from the error, bias and coverage figures above and from the table.
Method · historical final-three-week D/R general-election rows plus verified historical supplement; min n=5
Definition · bias_D is poll D-R margin minus actual D-R margin; positive overstates Democrats.
