**Incumbent Republican Zach Nunn faces Democrat Sarah Trone Garriott in Iowa’s 3rd Congressional District on November 3, 2026.** The suburban Des Moines-area seat carries an R+2 Partisan Voting Index and ranked among the nation’s most competitive House races after Nunn’s narrow 2024 reelection. Both candidates secured their parties’ nominations without opposition in the June 2 primaries, clearing the field for a head-to-head contest. Recent polling, including a Change Research survey, shows Trone Garriott competitive or ahead in head-to-head matchups while a generic Democrat leads a generic Republican by a slim margin, reflecting suburban voter responsiveness to national midterm conditions. Cook Political Report rates the race a toss-up or lean Republican, consistent with its historical closeness, yet prediction-market pricing places the Democratic nominee at 69.5 percent implied probability. Traders appear to weigh factors such as Trone Garriott’s state legislative record, consolidated Democratic support after earlier primary maneuvering, and broader midterm dynamics in swing districts more heavily than the incumbent’s narrow prior margin. Upcoming campaign developments, including television advertising and issue contrasts on health care and economic policy, will test whether these early signals hold through the fall.
