ABC News reports that Randy Niemeyer is projected to win the GOP primary in Indiana's 1st District. This primary wasn't competitive — the party establishment coalesced around Niemeyer — but the result is notable because the 1st District is Indiana's only congressional seat that's competitive in the general election. Niemeyer will now attempt to unseat Democratic Rep. Frank Mrvan in November in this seat that voted for Biden by just 8 percentage points in 2020.

ABC News is reporting that wealthy businessman Jefferson Shreve is projected to win the GOP nomination in Indiana's 6th District, east of Indianapolis, with 81 percent of the expected vote reporting. Shreve, who poured millions of his own wealth into the race and who recently lost a bid for mayor of Indianapolis, is a shoo-in in the general election to replace Rep. Greg Pence. With 28 percent of the vote, he's outpacing fellow Republicans Mike Speedy and Jamison Carrier.

We're tracking how female Democrats and Republicans are doing in Indiana's gubernatorial, Senate and House primaries. As I mentioned earlier, two out of the state's nine sitting House members are women, but the state has never had a female senator or governor.

Among Democrats, women are largely running in places where winning in November is a longshot; in many cases (like the gubernatorial race, and in the 2nd and 6th District), they were unopposed.

Among Republicans, Rep. Houchin has won reelection in the 9th District, and Rep. Spartz has won reelection too, in the 5th District, despite a well-funded challenge. In the 3rd District, Former Allen Circuit Court Judge Wendy Davis is trailing, but that race is still too close to call. And as we already reported, the sitting lieutenant governor, Suzanne Crouch, wasn't able to leverage that role into winning her party's nomination for governor.

ABC News is reporting that Spartz is projected to win the Republican primary in Indiana's 5th District. Spartz leads 39 percent to 33 percent over Goodrich with 92 percent of the expected vote reporting. It wasn't easy for "Hamlet from Hamilton" — Spartz announced in February 2023 that she wouldn't run for reelection, but changed her mind in February 2024 — but she now stands an excellent chance of returning to Congress in 2025 from her safely red seat.

ABC News reports that state Sen. Mark Messmer is projected to win the crowded GOP primary in Indiana's 8th District, which is currently held by Rep. Larry Buschon. Messmer defeated former Rep. John Hostettler and several other candidates in a race that attracted significant outside spending.
