5 further rows are held in this pollster’s history shard as within-party or nonpartisan contests (NYC-G · 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.

A missing sample, sponsor or source is labeled unavailable; it is never reconstructed.
