Christina Bohannan holds an 88% implied probability in the IA-01 House race because the Democratic challenger has established a consistent polling and fundraising edge over incumbent Republican Mariannette Miller-Meeks in this southeastern Iowa district. Miller-Meeks won the 2024 rematch by fewer than 800 votes in a seat that Donald Trump carried by a narrow margin, but 2026 midterm dynamics and Democratic strength at the top of the Iowa ticket have shifted nonpartisan ratings to Lean Democratic or Toss-up. Both candidates have raised roughly $7 million, while an independent candidate adds a modest vote-splitting factor. Recent events include Speaker Mike Johnson’s October rally for Miller-Meeks and an FEC complaint over a debate boycott, yet trader consensus continues to price Bohannan as the clear favorite heading into the November 3 general election.
