Statement of Methodology
This survey of 500 Iowa registered voters was conducted from August 20-August 23, 2026, and is based on live interviews of adults 18 years of age or older who indicated that they were either very or somewhat likely to vote in the November 2026 election for Governor and U.S. Senator. Each area's quota and demographic information including gender, race, education, age, and party affiliation was determined from 2020 exit polling data, 2020 Census data, the 2022 American Community Survey, and current voter registration statistics. Samples of both standard landline and cell phones were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each area were proportional to the number of adult residents in each area. The 99 Iowa counties were grouped into four general regions. The margin of error is +/- 4.4 percentage points. All surveys may be subject to other sources of error, including but not limited to, coverage error and measurement error. The bellwether of Muscatine County, Iowa was fielded August 17-19, 2026, with 300 likely midterm voters, and has a margin of error of +/- 5.6 percentage points.
