Indiana's 1st Congressional District — covering Gary, Hammond, East Chicago, and the Lake County corridor along the Illinois border — holds its 2026 primary on May 5. Democratic incumbent Frank Mrvan faces a low-key primary challenge while Republicans field a competitive 4-person race for the right to challenge him in November.
IN-01 is the most competitive Democratic-held district in Indiana and one of the NRCC's top 2026 targets nationally. Cook Political Report rates it Lean D. Mrvan has won by growing margins — 53.4% in 2024 — but the district has trended slightly toward Democrats over three cycles, and the NRCC views the Gary/Hammond corridor as targetable given its post-industrial demographics and legacy manufacturing base.
Trump attempted a mid-decade redistricting in late 2025 to eliminate the seat. The Indiana Senate blocked it 31-19, including more than a dozen Republican senators voting against Trump's preferred outcome. The maps remain unchanged. Mrvan's seat is intact for 2026.
On the Republican side, former state Secretary of Public Safety Jennifer-Ruth Green — who came closest to beating Mrvan in 2022 (losing by 5 points) — dropped out on February 6, 2026 after an ethics investigation. Porter County Commissioner Barb Regnitz immediately injected $1.5 million in personal loans and is now the overwhelming GOP frontrunner. She will likely face Mrvan in November in a race the DCCC is prepared to defend.

Background: North Township Trustee 2005–2021. BA journalism Ball State 1992. Former mortgage broker and pharmaceutical sales rep. Elected to Congress 2020, re-elected 2022 and 2024. Vice Chair, Congressional Steel Caucus. Member, House Appropriations Committee — which gives him real appropriations capacity relevant to the steel/manufacturing district. Son of Frank Mrvan Sr., long-time Lake County politician.
Platform 2026: Protect reproductive healthcare, grow the regional economy, protect the steel industry, protect public education, protect laborers, lower healthcare costs. No significant platform change from 2024. His focus on manufacturing and steel is highly district-relevant — Gary/Hammond is a legacy steel town.
Fundraising: $1,419,469 raised (as of Feb 2026 FEC report), $908,285 cash on hand. One of the best-funded House incumbents in Indiana. DCCC support expected.
TrackAIPAC: Mrvan is documented on trackaipac.com/congress. He has received pro-Israel lobby donations — classified as a moderate supporter, not a heavy recipient. No major IE spending documented.
Key vulnerability: The district is rated D+9 but has a large working-class Democratic base that sometimes splits. NRCC targeting him. His Appropriations seat is an asset but voters may not track it.
Background: Former member of the Gary Common Council. Gary is the heart of IN-01 — Lake County is the district's largest population center. Limited fundraising documented. Running against a well-funded three-term incumbent.
Platform: Limited public documentation. Campaign focused on Gary community issues, local economic development, and constituent service.
Viability: Very low. Mrvan is a three-term incumbent with $908K CoH and full party apparatus behind him. This is a primary challenge, not a competitive race.
Background: Porter County Commissioner. Ran for IN-01 in 2022 as a Republican — lost to Mrvan. No ethics issues documented. Re-entered the 2026 race after Jennifer-Ruth Green dropped out in February 2026 following an ethics investigation into Green's time as Indiana Secretary of Public Safety.
Fundraising: Kickstarted her campaign with a $1.5 million personal loan — the largest self-funding injection in the IN-01 Republican field. This gives her an overwhelming resource advantage over Walker, Mayers, and Schenke.
Platform: Prioritizing American families over foreign interests, reducing national debt, same-day in-person voting with paper ballots, immigration reform prioritizing safety and legal entry, anti-mandate healthcare policy, school curriculum reform. Moderate conservative framing.
TrackAIPAC: Not listed on TrackAIPAC candidates page. No documented Israel lobby exposure.
General election outlook: Regnitz will be the nominee. Cook rates the general Lean D — Mrvan has the structural and fundraising advantage, but NRCC targeting and Regnitz's self-funding make this a real race.
In late 2025, Trump pushed Indiana's Republican-supermajority legislature to redraw congressional maps mid-decade to eliminate Mrvan's IN-01 and André Carson's IN-07. The move was unprecedented — mid-decade redistricting to neutralize incumbent Democrats is extremely rare outside of court-ordered remaps. It triggered bomb threats and swatting calls against Republican senators who opposed the move. The Indiana Senate voted 31-19 to defeat the proposal, with more than a dozen Republicans joining all Democrats. The maps remain unchanged. This matters because it signals that even in a deep-red state, Mrvan's seat has enough structural legitimacy that 12+ Republican state senators refused to eliminate it on Trump's orders.
Green was the 2022 Republican nominee — she came within 5 points of Mrvan and was considered the strongest potential Republican challenger in 2026. She announced her campaign in October 2025 but resigned from her state position as Secretary of Public Safety following an ethics investigation. She dropped out of the 2026 race on February 6, 2026. Her departure dramatically changed the Republican primary dynamics — Regnitz moved from underdog to frontrunner overnight.

PoliVion scores every candidate on the same formula using only publicly available evidence — FEC filings, voting records, campaign websites, and published policy documents. Scores reflect transparency and governance capacity, not ideology, party preference, or polling position.
The scoring system has two layers: a Base Score from six weighted components, and an Integrity Penalty subtracted for documented donor conflicts, fraud-linked relationships, or foreign-interest exposure.
