Who’s ahead in the Iowa 4th District House race?

An updating average, accounting for each poll’s quality, recency, sample size and partisan lean.

Our average includes all candidates that FiveThirtyEight considers “major.” Candidates with insufficient polling data are not displayed in the averages. State polling averages are adjusted based on national trends, which means candidates’ averages can shift even in the absence of fresh state polls. Read more about the methodology.
