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.

Checking in on candidates of color running in Indiana

We're tracking how 11 candidates of color are performing in Indiana's gubernatorial, Senate and House primaries, and it appears that two are on their way to winning party nominations tonight. Democratic Rep. André Carson, of the Indianapolis-based 7th District, has 91 percent of the vote and is projected to win, according to reporting by ABC News. In the Democratic primary for Senate, clinical psychologist Valerie McCray is also projected to win, ABC News reports. She currently has 68 percent of the vote with 47 percent of the expected vote reporting — perhaps a bit of a surprise considering former state Rep. Marc Carmichael outraised her in that contest.

Beyond those two, however, it's looking unlikely any other candidates of color will find victory this evening. In the Democratic primary in the solidly red 4th District, insurance executive Rimpi Girn trails Derrick Holder, 63 percent to 37 percent, and ABC News reports that Holder is projected to win. In the 1st District, Mark Leyva and Ben Ruiz are behind Lake County Councilmember Randy Niemeyer by a significant margin in the GOP primary, with the winner set to take on Democratic Rep. Frank Mrvan. And in the solidly blue 7th District, Gabe Whitley is in last place among the Republican contenders fighting for the right to likely lose to Carson.
