ABC News reports that Valerie McCray is projected to win the Democratic primary for U.S. Senate. With 21 percent of the expected vote reporting, McCray has 67 percent of the vote over Marc Carmichael's 33 percent. McCray will face long odds against Rep. Jim Banks, the Republicans' one and only candidate on their primary ballot today, in November.

Over on Bluesky, Boston magazine contributing editor David Bernstein shared that the GOP has nominated men in all 10 open-seat solid-Republican districts going into tonight. A similar outcome for Democrats would be shocking, given that a vast majority of Democrats say that there are too few women in politics. But the GOP doesn’t share the same sentiment.

In 2020, we watched where Republicans were nominating women and found that, through August 2020, only 6 out of the 77 Republican women who had won their primaries did so in a safe Republican seat. A whopping 49 of those women won in safe Democratic seats.

In other words, the GOP women won primaries in places where they wouldn’t win in November. We’ll have more to say about that this year, after a few more primaries have passed.

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.

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.
