Voters across Northwest Indiana are heading to the polls Tuesday in the May primary, a high stakes day that will decide who carries each party’s banner in Indiana's 1st Congressional District.
On the Democratic side, incumbent Rep. Frank J. Mrvan is facing a challenge from LaVetta Sparks-Wade. Republicans are choosing among Porter County Commissioner Barb Regnitz, Ben Ruiz and Jim Schenke. Polls are open from 6 a.m. to 6 p.m. local time, with ballots counted after the doors close.
What's on the ballot
The primary lineup features Mrvan and Sparks-Wade on the Democratic ballot and Regnitz, Ruiz and Schenke competing on the Republican side, with county boards preparing to start tabulating votes once the 6 p.m. deadline hits, as reported by the Chicago Tribune.
Local voter guides from WFYI sketch out the issues the candidates are leaning on, from union jobs and health care to border security and election integrity. The Indianapolis Star has also published a voter guide breaking down the field and their stated priorities. Several campaigns that did not respond to media queries have instead pushed out platforms and updates through their social media pages.
Money and momentum
Federal Election Commission records show Mrvan's campaign committee reported roughly $1.09 million in cash on hand in its most recent filing, which covers activity through mid April, giving the incumbent a sizable organizational edge at the ballot box, according to the Federal Election Commission.
On the Republican side, Barb Regnitz has pumped a $1.5 million candidate loan into her own campaign and reported about $1.47 million in cash on hand, per her filing with the Federal Election Commission. That self funding has reshaped the tone of the Republican primary and made Regnitz the clear fundraising leader heading into tonight.
Why this race matters
The Cook Political Report rates IN-01 as “Likely D,” making it one of the few Indiana districts that national strategists still treat as competitive this year, according to the Cook Political Report. That keeps this slice of the Region on the national radar even if Democrats are favored on paper.
Local reporting has also highlighted a failed mid decade redistricting push last year that would have made the seat tougher terrain for Democrats. That proposal died in the state Senate, leaving IN-01’s current lines in place and under close watch, as outlined by the Indiana Capital Chronicle. Whoever emerges from the Republican primary will help determine how hard national parties lean into this corner of the Midwest in November.
When to expect results
Indiana law and county election notices set polling hours from 6 a.m. to 6 p.m., with county boards typically posting precinct returns soon after polls close and then rolling those into countywide and statewide totals.
The Indiana Secretary of State provides official guidance on polling hours and canvass procedures. Porter County has also posted a legal notice with its local details. Expect the first numbers to trickle in shortly after 6 p.m., with a much clearer picture by late evening as more precincts report.
What to watch tonight
Turnout in Hammond, Gary and other Lake County precincts will be pivotal for Mrvan, who is leaning on his base in those areas. On the Republican side, early returns will show whether Regnitz’s big financial bet actually turned into votes or whether Ruiz or Schenke managed to punch above their spending weight.
We will update this story as county boards and local outlets post returns.
