Indiana primary election results: Who won May 5 races for US House?

Voters chose candidates to run in November's midterms.

A state senate race in Indiana is getting major national attention.

Republican state senators who defied President Donald Trump's redistricting push saw losses in the May 5 primary election to counterparts backed by the president. The results show Trump's ongoing control of his party as he aims to secure the results Republicans need in November to maintain hold of Washington.

Here's what to know about Indiana's May primary and the results.

The White House involved in a state senate race

All nine of Indiana's congressional districts held primaries on May 5. The race came after Indiana state lawmakers shot down Trump's push for mid-decade redistricting in order to boost election odds for Republicans. The state legislature denied a redistricting bill in December 2025, making the Hoosiers the first to formally reject his push for mid-decade redistricting, according to IndyStar, part of the USA TODAY Network. That map would have cut up Indianapolis into four new districts, securing a Republican edge. Trump responded by endorsing challengers to state GOP lawmakers who voted against redistricting — and those candidates won on May 5.

The results were "surprising," Stewart says, given the degree to which state legislative races typically go unnoticed.

"State legislative races are quintessential local affairs," Stewart says. But the president's allies spent millions in those usually sleepy state legislative races, underscoring how far the White House is willing to go as GOP-controlled states across the country move rapidly to create new boundaries.

Of the seven GOP incumbents on the ballot who opposed the Hoosier State creating new boundaries for its federal delegation in Washington, only state Sen. Greg Goode prevailed, with most other GOP incumbents losing in landslides. In state senate district 23, the race has yet to be called as of Wednesday morning with incumbent Spencer Deery and Paula Copenhaver splitting the vote each at 50%, according to the Associated Press and CNN.

Here are the results in districts where standing lawmakers lost to Trump-backed GOP challengers, according to the Associated Press and CNN:

State Senate 1: Trevor de Vries beat incumbent Daniel Dernulc 75.1% to 23%
State Senate 11: Brian Schmutzler beat incumbent Linda Rogers 58.9% to 41.1%
State Senate 19: Blake Fletcher beat incumbent Travis Holdman 61.6% to 38.4%
State Senate 21: Tracey Powell beat incumbent James Buck 64.7% to 35.3%
State Senate 38: Incumbent Greg Goode holds against Brenda Wilson 53.5% to 36.1%
State Senate 41: Michelle Davis beat incumbent Greg Walker 58.58% to 41.2%

"The results are a sign that the Republican core regards the party as Trump’s," Stewart says.

That means the state's current congressional map held for the May primary, and Republicans don't have the padding they hoped for, giving Democratic candidates across the state windows of opportunity, as reported by IndyStar, part of the USA TODAY Network.

US House primary race results

Right now, seven of Indiana's U.S. representatives are Republicans and two are Democrats. The race comes as the GOP aims to maintain a narrow majority in the House in the November midterm elections and President Donald Trump stares down a dwindling approval rating.

Heading into Tuesday, several races stood out across the state's nine congressional districts. The 1st District featured a tight GOP race in a Democratic stronghold. In the state's blue-dot 7th District, there was a hotly contested Democratic primary, with incumbent Democrat Rep. Andre Carson looking to hold his seat representing the capital city.
