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.

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.
