The candidates are clashing over tariffs, gas prices and drug costs as both campaigns report millions in donations and cash on hand.
Rep. Mariannette Miller-Meeks and challenger Christina Bohannan face off in Iowa's closely watched congressional race, with voters heading to the polls Nov. 3 and affordability as the central issue.
Bohannan criticized the Trump administration's tariff policies for driving up costs, specifically citing 50% tariffs on Canadian goods; Miller-Meeks defended her support, arguing these policies help farmers secure better markets.
Miller-Meeks touted the "One Big Beautiful Bill" as a major tax cut, though Bohannan criticized the incumbent for opposing the Consumer Fuel Price Gouging Prevention Act amid Medicaid concerns.
According to the Federal Election Commission, Miller-Meeks maintains a slight lead with more than $7.2 million in total donations, while Bohannan leads in cash on hand with $5.2 million.
With Republicans currently holding a narrow 218-212 majority in the House, election-tracking outlets identify Miller-Meeks as one of the nation's most vulnerable incumbent Republicans.
