Democrat Christina Bohannan holds a clear lead in trader pricing for Iowa’s 1st Congressional District, reflecting recent district polls that show her ahead of incumbent Republican Mariannette Miller-Meeks by low-to-mid single digits. A July survey of likely voters gave Bohannan 40 percent to Miller-Meeks’s 35 percent, with independent Michael Bridgford at 11 percent. The race is rated a toss-up or lean Democratic by most forecasters, consistent with the district’s narrow 2024 margin and its mixed partisan lean. Both candidates secured their nominations comfortably in the June primaries, setting up a rematch in a seat where turnout patterns and national midterm dynamics favor the challenger. Traders appear to be weighting the consistent polling edge and historical midterm shifts more heavily than the incumbent’s name recognition.
