Christina Bohannan holds an 88.5% implied probability in the IA-01 House race because nonpartisan forecasters including Cook Political Report shifted the seat from toss-up to lean Democratic in early October, citing Democratic momentum in the midterm environment. The rematch pits the Democratic challenger, who lost narrowly in 2022 and 2024, against incumbent Republican Mariannette Miller-Meeks in a district with a narrow partisan lean. Recent polling averages show Bohannan ahead by roughly four points, supported by strong fundraising and advertising focused on tariffs’ impact on Iowa agriculture and corporate PAC influence. Miller-Meeks counters by linking Bohannan to progressive positions on crime and socialism. With the November 3 general election three weeks away, trader consensus prices the outcome as a likely Democratic pickup absent late shifts in turnout or national conditions.
