The AP is projecting that Fedorchak will win the Republican primary in North Dakota's at-large congressional district race. With 72 percent of the expected vote reporting, she has 46 percent of the vote so far. Her nearest challenger, Becker, has 29 percent of the vote so far.

We're also monitoring the GOP primary in the 1st District, a light-blue seat in and around Las Vegas held by Democratic Rep. Dina Titus. In the 2022 general election, Titus defeated Army veteran Mark Robertson by nearly 6 percentage points, but Robertson is back for another go. However, he's only raised $106,000, a figure dwarfed by restaurateur Flemming Larsen, a GOP rival who has brought in a whopping $1.8 million thanks to $1.5 million in self-funding. It's unclear if a recent report by the Nevada Independent disclosing that Larsen hired undocumented immigrants at his southern California restaurants will notably impact the race.

The AP now estimates that virtually all of the vote is counted in Ohio's 6th District, and the final-ish margin is Rulli 55 percent, Kripchak 45 percent. According to a weighted average of presidential results in this district, this is an R+32 district, which means Democrats overperformed here by a whopping 22 points.

Obviously, that's a very impressive performance by Democrats. However, one special election on its own doesn't necessarily mean anything. That said, the average of a party's overperformance in special elections for the cycle has historically been correlated with its performance in the subsequent general election, and that's good news for Democrats. On average this cycle, they have now overperformed in federal special elections by an average of 7 points — not Ohio 6th-level, but still quite solid.

It's 10 p.m. Eastern, and polls are now closed in the Silver State, our last primary state of the evening. Nevada law says that the state can't report results until the last voter in line has voted, so we may not see results right away. (But once we do, it will likely be a big chunk of the final tally.)

North Dakota Gov. Doug Burgum's retirement has precipitated an expensive and increasingly ugly Republican primary for governor between Rep. Kelly Armstrong and Lt. Gov. Tammy Miller. Armstrong is more familiar to voters, having served in Congress since 2019, while Burgum tapped Miller as his new lieutenant governor in December 2022. Both candidates have thrown around large sums of their own money: Based on financial reports though May 2 and large donations reported through June 7, about $3.8 million of the $4.2 million Miller has reported raising has come out of her own pocket, while Armstrong has self-funded almost $1.3 million of the $3.4 million he's collected.

Armstrong is the front-runner, having garnered endorsements from Trump and the state GOP. He also held a clear lead in three different surveys conducted in May, all of which showed him receiving close to 60 percent while Miller only attracted around 20 percent. Looking to gain ground, Miller has tried to link herself to Trump and Burgum, who's endorsed her. She's also run negative ads against Armstrong, including one that Rob Port of InForum described as "the most brutal" he'd seen in North Dakota that accuses Armstrong of insider trading and defending a child molester when he was a lawyer. Armstrong's campaign called the insider trading claim a lie, and the victims in the molestation case called for Miller to stop running ads about it. And Armstrong isn't without his own ad controversy, as his campaign ran a spot against Miller that included a citation from an artificial intelligence news website, which prompted Miller to criticize Armstrong for running "fake news" about her record.
