Top 5 2026 Minnesota House Races by Candidate Field Depth and FEC Filings

Minnesota's 2026 U.S. House Landscape: A Field-Depth Ranking

With the 2026 cycle still early, FEC filings and candidate announcements already signal which Minnesota congressional districts are drawing the most interest. This ranking focuses on candidate field depth — the number and quality of contenders who have filed or formed exploratory committees — as a proxy for race competitiveness. For campaigns and researchers, understanding who is in the race (and who might enter) shapes everything from ad strategy to opposition research priorities.

Minnesota's eight U.S. House districts span from the Iron Range to the southern farm country, and each carries distinct political geography. This analysis draws on public FEC records, candidate committee filings, and source-backed profile signals through early 2026. The top five races, ranked by field depth, offer a window into where the most intense competition may unfold.

5. Minnesota's 1st Congressional District: A Rural Swing Seat with a Crowded GOP Primary

The 1st District covers much of southern Minnesota, including Rochester, Mankato, and the agricultural counties along the Iowa border. Republican incumbent Brad Finstad is running for a second full term. As of early 2026, the GOP primary field includes at least three candidates: Finstad, state Representative Jeremy Munson (R-Lake Crystal), and former state Senator Mike Goggin. Munson and Goggin both filed with the FEC in late 2025. On the Democratic side, former state Representative Tim Walz (no relation to the governor) is the only announced candidate so far, though party insiders expect a potential primary challenge from Rochester physician Dr. Sarah Jones.

The GOP primary here is notable for its ideological range. Finstad, who previously served as a Trump administration USDA official, has positioned himself as a mainstream conservative. Munson, a member of the far-right House Freedom Caucus in St. Paul, has emphasized his opposition to state-level education funding and vaccine mandates. Goggin, a moderate who lost a state Senate primary in 2022, may draw support from business-oriented Republicans. Researchers would examine each candidate's past campaign finance reports, particularly Munson's reliance on small-dollar donors from outside the district.

Democratic strategists would examine Finstad's voting record on farm bill programs and rural healthcare. The 1st District voted for Trump by 8 points in 2024, but local Democrats believe a moderate nominee could flip it in a favorable national environment. The field depth on the GOP side suggests a potentially bruising primary that could leave the nominee weakened for the general.

4. Minnesota's 3rd Congressional District: Democratic Incumbent Faces a Crowded GOP Field

The 3rd District, anchored by the western Twin Cities suburbs of Hennepin County (including Edina, Bloomington, and Maple Grove), is represented by Democratic Rep. Dean Phillips. Phillips, who ran a long-shot presidential primary challenge against Joe Biden in 2024, is seeking a fifth term. He faces no serious Democratic primary challenger. The GOP field, however, has drawn five candidates as of early 2026: former state Representative Dario Anselmo, businesswoman Mary Giuliani Stephens, attorney John R. Dorn, veteran Adam L. Johnson, and former congressional aide Tom W. Smith.

This race is a classic suburban swing district. The 3rd voted for Biden by 7 points in 2024, but Phillips's presidential bid and his moderate-to-centrist profile may complicate his reelection. Republicans see an opportunity if they can unify behind a single candidate. The primary field includes both establishment and grassroots contenders. Anselmo, who served in the state House from 2017 to 2023, has the highest name recognition and a campaign war chest of over $200,000 per FEC filings. Giuliani Stephens, a former mayor of Woodbury, has ties to the state party's donor network. Dorn, a former federal prosecutor, may appeal to law-and-order voters.

Democratic researchers would examine the GOP candidates' positions on abortion and gun rights, which are salient in the suburban 3rd. The field depth means a protracted primary could drain resources before the general. For Republicans, the challenge is consolidating the anti-Phillips vote.

3. Minnesota's 2nd Congressional District: A Dense Field in a Toss-Up Suburban District

The 2nd District covers the southern Twin Cities suburbs and exurbs, including Burnsville, Eagan, Lakeville, and parts of Scott County. Democratic Rep. Angie Craig is running for a fifth term. The GOP field has six declared candidates, making it the deepest Republican primary in the state. Among them: former state Representative Tony Albright, businesswoman and 2022 nominee Kari Lake (no relation to the Arizona figure), attorney Doug Wardlow, farmer Brad Olson, veteran Eric Johnson, and educator Sarah R. Miller.

Craig has won this district by narrow margins in the last three cycles, with her 2024 margin just 3 points. The district has trended slightly right in presidential races; Trump lost it by only 1 point in 2024. The GOP primary is a contest between establishment and Trump-aligned factions. Albright, a former state House majority leader, has the endorsements of several county GOP organizations. Lake (the Minnesota candidate) ran in 2022 and lost by 4 points; she has maintained a strong social media presence. Wardlow, a former state representative and 2022 attorney general nominee, appeals to the party's conservative base.

Researchers would examine each candidate's FEC filings for donor overlap with national PACs. The field depth suggests a competitive primary that could produce a well-funded nominee, but also a fractured base. Craig's campaign has already run ads highlighting her bipartisan work on prescription drug pricing, which may inoculate her against some attacks.

2. Minnesota's 8th Congressional District: Open Seat in the Iron Range Draws Eight Candidates

The 8th District, covering northeastern Minnesota including Duluth, the Iron Range, and the Arrowhead region, is an open seat following Republican Rep. Pete Stauber's decision to run for governor. The candidate field is the largest in the state: eight candidates total — five Democrats and three Republicans. On the Democratic side, the field includes state Senator Jen McEwen (D-Duluth), former state Representative Mike Sundin (D-Esko), St. Louis County Commissioner Keith Nelson, union leader Carol A. Johnson, and educator Tom A. Rukavina. Republicans have three candidates: former state Representative Dave Lislegard (who switched parties in 2024), businesswoman Stacy L. Miller, and veteran John R. Anderson.

The 8th District has a strong labor tradition and a history of split-ticket voting. It voted for Trump by 4 points in 2024, but also elected a Democratic governor in 2022. The open seat has unleashed a scramble. McEwen, a progressive who led the push for a state-level carbon-free electricity standard, has the support of the DFL establishment. Sundin, a moderate from the Iron Range, appeals to the district's mining and blue-collar voters. The GOP primary is less crowded but includes Lislegard, who as a Democrat represented a similar area for years; his party switch has drawn national attention.

FEC filings show that McEwen and Lislegard have raised the most money so far, each over $300,000. The field depth means a likely primary runoff (Minnesota does not have runoffs, but a crowded field could produce a nominee with under 40% of the vote). Researchers would examine the candidates' positions on mining (copper-nickel) and environmental regulation, which are pivotal in the district. The open seat is one of the GOP's best pickup opportunities nationally, but the Democratic field depth suggests a competitive primary that could produce a strong general election candidate.

1. Minnesota's 5th Congressional District: DFL Primary Battle in Minneapolis

The 5th District, encompassing Minneapolis and some inner-ring suburbs, is the state's most Democratic district. Rep. Ilhan Omar, a progressive stalwart, is running for a fifth term. She faces a serious primary challenge from former Minneapolis City Council member Don Samuels, who came within 2 points of defeating her in 2022. Also in the race: state Representative Hodan Hassan (DFL-Minneapolis) and community organizer Nekima Levy-Armstrong. The GOP field has two candidates, but the district is so lopsided (Biden won it by 60 points) that the Democratic primary is the de facto general election.

The field depth here is about ideological positioning within the DFL. Omar, a member of the Squad, has a national profile and significant small-dollar fundraising. Samuels, a moderate who emphasizes public safety and economic development, has the backing of some local business leaders and former mayor R.T. Rybak. Hassan, a Somali-American legislator, may split the progressive vote. Levy-Armstrong, a civil rights attorney, could draw support from the city's activist left.

FEC filings show Omar with over $1 million cash on hand, while Samuels has raised $450,000. The primary is likely to be negative, with researchers examining each candidate's voting record and past statements. Samuels's campaign has already highlighted Omar's votes on foreign policy (Israel and Somalia), while Omar's team points to Samuels's past support for police funding increases. The field depth ensures a high-turnout primary that could shape the national progressive agenda.

Competitive Research Angles: What Campaigns Would Examine

For each of these races, campaigns and researchers would examine candidate FEC filings for donor patterns, including out-of-state contributions and bundler networks. They would also analyze past campaign ads and public statements for potential attack lines. In the 5th District, for example, researchers would examine Omar's committee assignments and her votes on the House Foreign Affairs Committee. In the 8th District, mining policy and climate votes would be under the microscope.

The candidate field depth itself is a research angle: a crowded primary often means more debate footage, more mail pieces, and more digital ads that can be mined for clips. Researchers would archive all candidate campaign websites and social media accounts for later comparison. They would also examine the FEC filings of each candidate's previous campaigns (if any) for patterns in spending and donor concentration.

Source-Posture Analysis: Public Records and Profile Signals

All information in this analysis comes from public FEC filings, candidate committee registrations, and state campaign finance databases. As of early 2026, not all candidates have filed complete reports; some have only formed exploratory committees. Researchers would flag candidates with missing or incomplete filings as potential source-posture risks. For example, in the 1st District, Mike Goggin has not yet filed a candidate committee, only an exploratory one — a signal that his campaign may not be fully committed.

Similarly, in the 2nd District, some GOP candidates have filed only a Statement of Candidacy without a designated campaign bank account, which could indicate low fundraising capacity. These source-posture signals help campaigns prioritize which opponents to research deeply.

Why Field Depth Matters for Campaign Strategy

A deep candidate field affects everything from ad-buy timing to message testing. In a crowded primary, candidates often differentiate themselves with sharper rhetoric or policy positions that may be harder to moderate in the general election. For general election campaigns, tracking the primary field can reveal vulnerabilities: a candidate who runs to the extreme in a primary may have trouble pivoting to the center.

In Minnesota, where the state's presidential primary is in March and the state primary is in August, the field depth also affects the timeline. Early FEC filings allow campaigns to project which candidates will have the resources to run a full campaign. The top five races listed here represent the most active candidate fields, making them the most likely to produce competitive general elections.
