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.

CORRECTION (May 8, 2024, 11:12 a.m.): A previous version of this blog entry misidentified Indiana 6th District Republican primary candidate Jamison Carrier as Jamison Crowder.

Spartz came into tonight as clearly one of the most endangered incumbent House members in the country. But with her primary victory, still just one incumbent has met defeat so far this primary season: Republican Rep. Jerry Carl, who lost in an incumbent-versus-incumbent clash in Alabama on March 5 against Rep. Barry Moore due to redistricting pushing the two into the same dark red seat. However, there are many months to go before all primaries are completed, so definitely do not rule out another incumbent going down in a primary.

So far in 2024, the GOP seems to be running behind where it was last cycle when it comes to nominating women in competitive or safe seats. Tonight, female incumbents Houchin and Spartz held on and will very likely win reelection in the fall. But a couple qualified female candidates didn’t fare as well tonight. The sitting lieutenant governor, Crouch, lost the gubernatorial primary, and in the 3rd District, it looks like Davis also failed to win. Both of these women could’ve benefited from more unified support. Although Crouch had endorsements from lower level officials, the Club for Growth and Trump endorsed Braun. And in the 3rd, the Club for Growth actively campaigned against Davis. Women, especially Republican women, face many invisible hurdles in their effort to win elected office. Add hurdles like these, and the challenge is insurmountable.

Braun was the front-runner in the Republican gubernatorial primary tonight, and he ended up winning. But the candidates weren’t that different on many of the issues. As other observers noted, the primary was fought more over big national issues like crime, China, immigration and abortion than over the day-to-day running of the state. The way the race unfolded tells us a lot about the direction of the Republican Party nationally, and the candidates we can expect deep-red states like Indiana to send to Washington. Among other things, that’s meant that the party continues to run conservative anti-abortion candidates despite the position being unpopular, and an often losing one, for Republicans in general.

Another ex-congressman may make a comeback in southwestern Indiana's 8th District — once one of the most competitive seats in the country but now a reliably Republican seat. The two front-runners in the GOP primary here appear to be state Sen. Mark Messmer and former Rep. John Hostettler. Establishment and tea party Republican groups have invested heavily in this race: America Leads Action has spent $1.6 million to help Messmer and hurt Hostettler, and Protect Freedom PAC is airing ads for Hostettler.

But the main divide in this race seems to be less about governing philosophy and more about foreign policy. For instance, Protect Freedom PAC — which represents former Rep. Ron Paul's libertarian wing of the party — may be with Hostettler because he and Paul were two of only six Republicans who opposed the Iraq war back in 2002. And Hostettler's record on Israel has provoked strong opposition from the American Israel Public Affairs Committee and Republican Jewish Coalition. Citing anti-Israel votes Hostettler took in Congress as well as a book he wrote that blamed the Iraq war on Jewish Americans' efforts to help Israel, these two groups have dropped $2.2 million to attack Hostettler or boost Messmer.

In total, pro-Messmer, anti-Hostettler outside groups have outspent pro-Hostettler, anti-Messmer groups by a whopping $5.1 million to $793,000. (And it's not like Hostettler himself has been able to fight back; Messmer has outraised him $763,000 to $41,000.)

Don't write off two other candidates, either. Surgeon Richard Moss, who has pledged to join the Freedom Caucus, has raised $556,000, while 28-year-old Army reservist Dominick Kavanaugh took in $528,000. That said, given the financial disparity, any candidate other than Messmer has to be considered an underdog.
