THE RACE AT A GLANCE
Attorney general: a close polling picture.
Reviewed October 20, 2026
Brenna Bird (R), the incumbent, faces Nate Willems (D). The latest verified survey puts them 0.5 points apart, with one in five voters undecided. That is not a meaningful lead given the poll’s uncertainty.

ANALYST ASSESSMENT
Leans Republican
Louis Jacobson, August 20, 2026, moved Iowa from “Likely” to “Leans Republican.” This is his assessment in Sabato’s Crystal Ball, not one of the publication’s formal race ratings.

All polls, source details & limitations
Cygnal conducted both polls for Iowans for Tax Relief Foundation using live-phone and SMS interviews with known registered voters, weighted to a likely general-election electorate. Attorney general is question 13 in each original report. The sponsor is an advocacy organization; sponsorship is disclosed so readers can assess the evidence.
The reported margins of error apply to each survey, not directly to the difference between candidates. Sampling error is only one source of uncertainty. Question wording, weighting, turnout and nonresponse also matter. The 2022 margin is calculated from the official canvass including 801 write-in votes; shares rounded to two decimals yield Bird 50.82% and Miller 49.11%.
Coverage: two verified public head-to-head polls located through October 20. No newer verified attorney general poll was located in this review. This is not a claim that unpublished or inaccessible surveys do not exist. Commentary, markets and past results remain separate from polling and do not alter contest scoring or automatic-pick rules.
Additional context: name recognition & older reported polls
September Cygnal survey, Bird favorability: 19.3% favorable, 29.8% unfavorable, 20.6% no opinion and 30.3% never heard of her (question 8). June: 23.5%, 24.9%, 18.6% and 33.0%, respectively. These are from the same two surveys above, not additional polls. No equivalent Willems measure was verified, so this is not a candidate-to-candidate favorability comparison.
Older publicly reported polling with incomplete methods or ballot details is not included in the numerical chart. A November 2025 Forward Iowa Education Fund memo reports 41% Bird, 41% Willems and 17% undecided, a 99% rounded total; it does not establish the full methods needed for this series.
