Incumbent Democratic U.S. Rep. André Carson won the primary for Indiana's 7th Congressional District, a safely Democratic Indianapolis-area seat he has held for nine terms. In parallel GOP state Senate primaries, eight incumbents who opposed a congressional redistricting plan faced challenges, with Donald Trump endorsing seven and allies spending over $6 million; one incumbent was defeated. The redistricting proposal aimed to add two Republican House seats but was blocked in a December vote.
