Iowa governor polls
Reported survey matchups, with the original sources and methodological details. Names tested in a survey are not a certified candidate list.
What do the polls say?
Hover or tap a date to see the survey and source.
Dots show reported support. Lines connect surveys over time—not an average or forecast. Pollsters can differ. Missing values and multiple surveys ending on the same date break the lines.
How to read this chart
No average, trend estimate, or win probability. Different matchups and populations are not combined. Dates mark the last day people were surveyed. The vertical scale always starts at zero; use “Full 0–100% scale” to compare charts on the same scale. The number of people surveyed is the survey sample size, not the number supporting a candidate. Select “Survey source” to inspect every report, including overlapping dots.
