Latest reporting on the Indiana Republican state Senate primaries (May 5, 2026) says Trump-backed challengers defeated multiple GOP incumbents, with several results already called and at least a couple races reported as extremely close/unresolved late in the count.[1][2]
What major outlets are reporting
- Multiple incumbent GOP senators lost their primaries in contests where Republican incumbents faced Trump-backed challengers, according to coverage published in early May 2026.[2][1]
- One late-breaking example reported by NBC News: State Sen. Spencer Deery and Paula Copenhaver were reported as tied/near-tied late Tuesday night, with Deery leading by only three votes in the version of the report available at the time.[2]
- Coverage also highlights that these races were tied to intra-party conflict over mid-decade redistricting, with six of the seven GOP state senators on the ballot who faced Trump-backed challengers losing their primaries (projected/reported) in that NBC News reporting.[2]
Named races mentioned in coverage
The WRTV report lists several specific primary matchups and winners, including (among others) incumbents losing to challengers such as:
- Blake Fiechter defeating state Sen. Travis Holdman
- Michelle Davis defeating state Rep. Greg Walker
- Tracey Powell defeating state Sen. Jim Buck
- Brian Schmutzler defeating state Sen. Linda Rogers
- Greg Goode holding off a challenge from Trump-backed Brenda Wilson
- Additional races described as too close to call at the time of publication[1]
If you tell me what you mean by “latest”
Do you want:
- a race-by-race results roundup (with who won each Senate district primary), or
- an explanation of what drove the losses (e.g., redistricting, Trump endorsements, spending/attack ads)?
Reply with which option you prefer and (if you know them) the counties/district numbers you care about most.
