Here's a good question from our fellow election nerds over at Daily Kos Elections. What say you guys?

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.

OK, after an action-packed night of Republican primaries, we’re calling it a night on here! It was a good night for embattled incumbents, establishment-backed pragmatists and supporters of Israel. Here’s a rundown of who won all the major Indiana races:

- Sen. Mike Braun walked into the Republican primary for governor as the favorite, and he walked away with the victory, despite his opponents’ strong fundraising and attacks against him. The truth is, though, there weren’t huge differences between the candidates on most issues.

- The closest race of the night was the GOP primary for Indiana’s 3rd District. ABC News is not yet reporting a projection in that race, but other outlets (such as the AP) have called it for former Rep. Marlin Stutzman. The conservative hardliner beat out several other candidates, including more moderate former Judge Wendy Davis and businessman Tim Smith.

- The one incumbent under threat tonight was Republican Rep. Victoria Spartz in the 5th District, but Spartz held off state Rep. Chuck Goodrich in her primary. Spartz had waffled on whether she’d run for reelection, having originally said in February 2023 that she wouldn’t seek another term. But this past February, she decided just before the filing deadline to run again, and she overcame Goodrich’s sizable financial edge to win renomination.

- In Indiana’s 6th District, wealthy storage company owner Jefferson Shreve outpaced a crowded Republican field. Aided by millions in self-funding and residual name ID from his recent and expensive run for Mayor of Indianapolis, the moderate Shreve outpaced more conservative candidates Mike Speedy and Jamison Carrier. He’ll be a shoo-in in the fall to replace retiring GOP Rep. Greg Pence.

- State Sen. Mark Messmer won a comfortable victory over a crowded GOP field in Indiana’s 8th District. The race attracted some national attention because a pro-Israel super PAC pumped seven figures into defeating another GOP candidate, former Rep. John Hostettler, who often voted against aid to Israel when he represented the area in the 1990s and 2000s. Messmer ultimately outpaced Hostettler by 20 percentage points and will be heavily favored in the general election this fall.
