Our poll-of-polls for Iowa's 2026 statewide and congressional races, built the plain way
RealClearPolitics
always did it: a simple, unweighted average of the recent public polls —
no pollster ratings, no house-effect nudges, no black box. Every poll in
the average is listed below — with a link to the pollster's own release
wherever one is public — so you can add it up yourself.
Statewide · Governor and U.S. Senate
U.S. Senate
2026 general election · 15 polls in the average · Sep 23–Oct 22, 2026
Josh Turek (D) 46.1
Ashley Hinson (R) 46.0
Turek +0.1
7.9% undecided or other, on average.
Faded dots are individual polls. The bold line is the running
average, built on each date the same way as the headline figure
(polls from the previous 30 days, or the three most recent when
fewer fell inside that window), so it ends at the figure above.

Not polled · the down-ballot statewide races
No public head-to-head polling exists for these 5
races — pollsters rarely cover them. The candidates and their money
are on each race page.
How this is built. The average is a simple mean of every
poll whose field work ended within 30 days of the most recent one. When
that window holds fewer than three polls we fall back to the three most
recent polls whatever their age, and where a race has only one public poll
we show that poll alone — labeled, with no lead figure, because one poll
is not an average and may be many months old. When the top two are level
we say tied rather than naming a leader. A poll announced before its
results are public is listed, marked, and left out of the average until
the numbers exist. We don't weight by pollster,
sample size, or recency, and we don't adjust for a pollster's partisan
lean — sponsored polls are labeled and counted the same as everyone
else's, exactly as RCP did. Only statewide and congressional races are
here: there is no reliable public polling at the individual
state-legislative-district level, so the
district terrain leans on registration and money
instead. Numbers transcribed from Wikipedia's cited polling tables; each
row links to the original release. Generated 2026-10-24.
