Indiana primaries 2024: Spartz survives, big spenders prevail

538 tracked several establishment-versus-insurgent GOP primaries.

Tuesday saw the resolution of several major Republican primaries in Indiana: Voters selected the men who will likely become the state’s next U.S. senator and governor, and three open U.S. House seats were the canvas for fierce primary battles between the establishment and populist wings of the GOP. A maverick Republican incumbent also successfully defended her seat after waffling over her decision to seek reelection.

538 reporters and contributors broke down the election results as they came in with live updates, analysis and commentary. Read our full live blog below.

Indianapolis’s Marion County is reporting votes now in Indiana’s 6th, too. And according to the AP, Shreve is beating Speedy there 38 percent to 29 percent, likely cutting off any chance for the more conservative Speedy to prevail.

Banks largely unknown to Indiana Republicans

You're right, Irena. Banks is favored to win in November due to the state's partisan lean, but interestingly, many Hoosiers don't yet know anything about him. Because the Senate primary was uncontested, Banks hasn't had a chance yet to define himself to voters. According to an April poll from SurveyUSA/Howey Politics Indiana/State Affairs, 55 percent of Republican primary voters in the Hoosier state were not familiar with him. Of the remaining 45 percent, 34 percent said they had a favorable opinion of Banks, and 10 percent said they had an unfavorable opinion.

Spartz has early edge in 5th District GOP primary

Checking in on Rep. Victoria Spartz, the most endangered incumbent we've got our eye on, and she's out to an early lead in the 5th District Republican primary — but one that's far from insurmountable. With 23 percent of the expected vote reporting, Spartz leads Chuck Goodrich 40 percent to 32 percent. There's quite a ways to go, but Spartz does lead in the three counties that have reported any votes, including Hamilton, the sizable Indianapolis suburban-exurban county that will likely make up close to half the primary vote in this district.
