Mariannette Miller-Meeks (IA-1), a Republican, is seeking reelection. Her district is considered a  “Toss Up Republican” according to The Cook Political Report. Miller-Meeks, with nearly $1.5M raised, is being challenged by Christina Bohannan, who has raised over $2.7M. In IA-3, Sarah Trone Garriott (D) has raised over $1.3M; the race is rated a “Toss Up Republican”.

Lindsay James, a Democratic woman, leads her party’s field in fundraising with $440,092. No Republican women reported campaign finance data in IA-4, which The Cook Political Report considers solidly Republican. Five men from the Republican party reported campaign finance data.
