Recent polling averages and nonpartisan forecaster updates have positioned Democrat Christina Bohannan ahead of Republican incumbent Mariannette Miller-Meeks in Iowa’s 1st District rematch. July surveys showed Bohannan leading by 3–5 points, while Cook Political Report, Inside Elections, and Sabato’s Crystal Ball each shifted ratings toward Democrats in early October, citing the seat’s narrow 2024 margin and broader competitive dynamics. Both candidates have raised roughly $7 million, with primaries confirming their nominations in June. Speaker Mike Johnson’s October rally for Miller-Meeks highlighted ongoing Republican efforts to defend the district, though trader consensus reflected in current pricing aligns with the Democratic edge in this southeastern Iowa battleground ahead of the November 3 general election.
