Mariannette Miller-Meeks (R-inc.) vs. Christina Bohannan (D)
I. The Race

Mariannette Miller-Meeks (Republican) is running for a fourth term in the U.S. House, and has won two of her three terms by insanely close margins. She had previously run for the seat when it was designated IA-2, but lost to Dave Loebsack all three times she was the GOP nominee. She finally got in when Loebsack retired.
Christina Bohannan (Democrat) is a former Iowa State Representative who is nearly as persistent as Miller-Meeks; Bohannan has lost to her two times in a row, and is confident that the third time will be a charm this November.
II. District Geography

Iowa’s 1st Congressional District (IA-1) is made up of the southeastern quadrant of the state. As you can see, it has undergone a drastic political reformation since 2008:


The district resembles northern Illinois and Wisconsin politically far more than it resembles Missouri or Nebraska, which influence the western half of the state. Obama carried the current boundaries by 16 points in 2008, and then by 14 in 2012 as Iowa inched toward Romney in a statewide loss. Here were President Trump’s margins:
2016 Trump +3%
2020 Trump +2.9%
2024 Trump +8.5%
The political hurdles for Republicans in the district, especially normal Republicans like Miller-Meeks without Trump’s white working class superpowers, are Johnson County and the University of Iowa (Harris +37.8%), and Scott County, which contains Davenport. Racial demographics appear favorable but there is a long-standing blue-collar Democrat faction here.
Key Statistics
83.4% White, 5.6% Hispanic, 4.5% Black
66.4% Urban, 33.6% Rural
III. Market Assessment
Ouch. Looks a lot like NE-2, with bettors not expecting much out of Miller-Meeks.
IV. History
Democrat Dave Loebsack secured one of the party’s biggest upsets in 2006, knocking off incumbent Republican Jim Leach. He went on to defend the seat six more times, which included three wins over Miller-Meeks (including one in which he beat her like a drum in 2008). Without Trump on the ticket in 2018, Loebsack expanded his margin by 4.8% from the previous presidential election:

Once Loebsack finally retired, Miller-Meeks came back into the picture and rode a Trump statewide win to a razor close victory over Democrat Rita Hart – a margin of just six votes out of nearly 400,000 cast.

Her first meeting with Bohannan occurred in the 2022 GOP House takeover, and Miller-Meeks rode Kim Reynolds’ incumbent coattails to a 6.8% margin. One might think that with Trump destined to win Iowa by more than 13 points and IA-1 by 8.5%, Miller-Meeks would have another easy election against Bohannan:

That assumption would constitute a wild miss; Miller-Meeks secured her seat in a very narrow GOP majority by 799 votes out of more than 400,000 cast. She has won two of the closest U.S. House races this century in a span of just three elections. This does not bode well for her in a year that is fundamentally more favorable to Democrats than a cycle in which Republicans are out of the White House.
V. Analysis of 2026 Primary Results

Miller-Meeks took on a primary challenger who posted a respectable share (28.4%), and Bohannan took out her opponent easily. No lingering drama from the primaries persists.
VI. Polls
Polling data pulled from The New York Times:

The Bullfinch Group is to polling credibility what Nickelback is to fine music, but even a blind squirrel finds an acorn now and then. Bohannan leads by 4.5% in an average of the two polls I found.
VII. Media Ratings

Cook remains hesitant to take a stance on the race, but the other three favor Bohannan by various degrees.
VIII. Party Registration

This is a mixed bag. Because there are more total active voters registered in the district, the Republican lead as a percentage has fallen by 0.3% despite a gain in the raw lead. This likely tracks with independent sentiment dragging results to the left this year and favors Bohannan.
IX. Election Considerations
One thing is for certain, and that is that Iowa runs excellent elections. A lot of this is owed to the current treasurer, Roby Smith, who started turning the screws on election reforms as a state legislator before the 2020 election. Iowa has manageable early voting windows, control over the mail-in balloting process, and a voter registration system that doesn’t automatically register voters.

X. Summary and Election Estimate
Miller-Meeks is in a tough spot, and it makes sense why the Republican Party is triaging her race.
TRIAGE NEWS: The Congressional Leadership Fund and Trump’s super PACs are cutting off their first GOP incumbents in NJ-7 and IA-1 as the party races to avoid more widespread losses in final three weeks. Also giving up OH-1 and MI-8.

In examining all of the decisive seats, IA-1 leaps off the page as one of (if not the most) likely losses of the entire field. Miller-Meeks is an uncharismatic candidate with two “scraper” election wins in the past three races. The first, the win of just six votes, took place with Trump on the ballot. Her second win was propped up by Kim Reynolds winning a GOP-favorable midterm reelection race by more than 20. Her win in 2024 was by less than a point, with Trump winning the district with a Reagan-like performance.
Unfortunately, I think she’s toast. Here is my matrix to support the decision:

Bohannan has made enough public comments to prevent the DSA scare from setting in. She has been critical of Biden on the border and sticks mainly to center-left Democrat reforms, realizing she’s in a Trump +8.5% district. Additionally, the district has a very white population, which is much more likely to turn out and vote and be pushed into the standard political winds of a midterm. This means there isn’t much of a low-propensity minority coalition here likely to sit out and give a huge hand to Miller-Meeks. The incumbent’s only hope here is for the University of Iowa to be completely checked out and have very little elasticity present in the MAGA coalition.
