While it’s well known that McCormick used to be a Republican before switching parties in 2021, it’s perhaps less well known that Braun also used to be registered with the opposite party.

Braun was registered as a Democrat until the 2012 cycle, perhaps a surprise for a politician ranked among the most conservative in the Senate based on DW-NOMINATE. In 2018, when he ran for Senate, he told CNN that he was only registered as a Democrat in order to vote in local primary elections and that he has always identified as a Republican regardless of his registration status.

In any case, at least according to the official records, the governor’s race in Indiana looks like it will be between two party-switchers, perhaps emblematic of the upheaval in partisan alignment we’ve seen across the nation in the last decade.

As I mentioned earlier, the Republican races throughout the state are crowded with anti-abortion candidates. Checking in with the early results, it looks like ABC is reporting that one incumbent on the list, Baird in the 4th District, is projected to win. ABC News is also reporting that Houchin, who currently represents the 9th District, is projected to win in her primary and will go on to seek reelection in November.

We’ve got a few votes counted in the 8th District as well (8 percent of the expected vote, to be precise), which sits in the southwestern corner of the state. This seat attracted a fair bit of outside spending, both in support of Mark Messmer, the state senator currently leading the bunch, and against former Rep. John Hostettler, who represented a predecessor district in the 1990s and 2000s. The race was notable in that it represented the first time AIPAC’s affiliated super PAC, United Democracy Project, got involved in a Republican primary. Previously, it had only spent in Democratic primaries.

With 12 percent of the expected vote reporting in the Republican primary for the 3rd District, Zay is at 29 percent, Stutzman is at 21 percent, Davis is at 18 percent and Smith is at 17 percent. However, Zay’s lead is likely due to the fact that Huntington County, where a lot of the reported votes are coming from, is in his state Senate district. The Associated Press has results from more counties, including populous Allen County, and currently has a different result: Stutzman 23 percent, Davis 22 percent, Smith 21 percent and Zay 19 percent.

Tonight, we'll be monitoring how candidates of color perform in primaries for governor, U.S. Senate and the U.S. House of Representatives. Overall, 11 people of color are running in these contests — six Republicans and five Democrats.

The most likely primary winner is Democratic Rep. André Carson, who is Indiana's lone Black representative on Capitol Hill (and was also only the second Muslim ever elected to Congress). Democrats in the solidly blue 7th District look set to renominate him against two little-known Black Democrats.

In the dark-red 4th District, insurance executive Rimpi Girn is an Indian immigrant who has raised at least a little money, so she may be the favorite for the Democratic nomination — but a November defeat against GOP Rep. Jim Baird is a near-certainty.

In the Democratic primary for U.S. Senate, clinical psychologist Valerie McCray is running a long-shot race to become the state's first Black U.S. senator. She ran for the state's 2022 Senate contest but failed to make the ballot and briefly ran for president in 2020. However, she's raised only $14,800, less than the $112,000 former state Rep. Marc Carmichael has brought in. Still, either Democrat will be a huge underdog against Rep. Jim Banks in the general election.

It's less clear if any candidate of color has a shot at winning a GOP primary. On paper, the contender with the best chance might be "Honest Gabe" Whitley, who has raised $364,000 in the solidly Democratic 7th District, making him the only Republican in that race to have reported raising anything. But Whitley is a lightning rod of controversy: Among other things, he faces accusations of concocting false donors and a fictional veterans organization to back his candidacy.

In the 5th District, speech-language pathologist and business owner Raju Chinthala is running, but he's unlikely to finish ahead of the incumbent Spartz or her leading challenger, Goodrich. Two Republican Latino candidates are running in the 1st District — Mark Levya and Ben Ruiz — but Lake County Councilmember Randy Niemeyer is the party's preferred candidate to take on Democratic Rep. Frank Mrvan.

Lastly, the best-known Republican on this list is Curtis Hill, who is making a long-shot bid for governor. Hill lost renomination for state attorney general in 2020 after allegations came out that he had groped a group of women at a party.
