Who's In the Race

After advancing from the May 5 primaries, Democrat Frank Mrvan, the incumbent representative, and Republican Barb Regnitz, a Porter County Commissioner from Valparaiso, will face each other during the general election on Nov. 3 for Indiana's 1st U.S. House District.

Mrvan won the Democratic primary with about 80 percent of the vote, collecting 42,519 votes against one opponent. Regnitz won a three-way Republican primary with about 46 percent of the vote, or 13,007 votes, beating her two opponents by roughly 16 percentage points.

What They Stand For

Frank Mrvan (Democrat)

Mrvan's campaign website lists reproductive healthcare access as a top issue, stating he is "committed to protecting Women's access to reproductive health care and supports the codification of Roe," and that he is fighting against proposed federal abortion bans following Indiana's statewide abortion ban after the Supreme Court's *Dobbs* decision.

On the economy, his campaign site describes him as "growing the regional economy by advocating for good-paying jobs, and protecting the steel industry from bad actors around the globe," with a focus on Buy America protections and opposing illegally subsidized foreign steel imports, a direct concern for Northwest Indiana's manufacturing base. He also emphasizes border security, framed around public safety and drug interdiction.

His House office issues page highlights work on lowering prescription drug costs for seniors, mental health services for veterans, and support for pregnant women in need of care. Constituent testimonials on his campaign site also point to infrastructure investment and public education as priorities.

Barb Regnitz (Republican)

Regnitz's campaign platform centers on what her official campaign website describes as "safe cities, secure borders and smarter spending." Border security is her lead issue: she calls for stopping illegal crossings, drugs, and human trafficking, supporting law enforcement and border agents, ending "catch-and-release" immigration policies, and building a border wall and denying funds to sanctuary cities.

Reducing federal spending and the national debt is a core plank. Fox 59, summarizing her campaign website, reported she has emphasized bringing "fiscal discipline and real results to Washington."

Her platform includes a call for "100 percent election integrity" through in-person voting and watermarked paper ballots, as quoted by WVPE and WFYI from her official site.

The WFYI general election voter guide from Sept. 21 reports that Regnitz's stated priorities include education, national security, and affordability. The Indiana Capital Chronicle's primary voter guide noted her website "echoes many of the initiatives of the Trump administration, including making America's borders safe again and making Americans healthy again." Battleground Vote also notes she supports maintaining a strong military and prioritizing American families over foreign interests.

The Money Behind the Race

GIVEGREEN UNITED ACTION is the only committee that has reported independent expenditures in the race, spending $53,330 in support of the Democratic nominee. No opposition spending has been reported in this race.

The figures cover periodic Federal Election Commission (FEC) reports through Sept. 21, plus 24- and 48-hour notices through Sept. 28.

Race Outlook: Ratings and Betting Markets

Three major race-rating services all classify this contest as "Likely Democratic": the Cook Political Report as of Sept. 25; Sabato's Crystal Ball as of Sept. 22; and Inside Elections as of Sept. 17.

The prediction market Kalshi put the probability of a Democratic win at about 97 percent as of Sept. 28, based on a trading volume of 29,616 contracts. The Republican probability stood at roughly 2.5 percent.

Mrvan won this seat in both 2022 and 2024, taking about 53 percent of the vote in 2022 and about 53 percent in 2024. Statewide, Indiana leans heavily Republican: in both 2022 and 2024, Republicans won seven or eight of the state's nine U.S. House seats and the U.S. Senate race on the ballot, with Senate winners clearing nearly 59 percent of the vote. In the 2024 presidential race, Donald Trump carried Indiana with about 59 percent of the vote.

The 1st District is the exception to Indiana's statewide Republican dominance. It is one of only two congressional districts in the state that Democrats have carried in each of the last two cycles, making it a Democratic island in an otherwise deep-red state.
