South Carolina, Nevada, North Dakota primaries and Ohio special election 2024: Nancy Mace, Sam Brown win

Democrats nearly won a safely Republican congressional seat.

June 11 was another packed primary day, as voters in South Carolina, Maine, North Dakota and Nevada weighed in on who will make the ballot this fall. We had our eyes on a slew of Republican primaries on Tuesday, including several competitive contests for U.S. House seats, as well as contests to pick Nevada's GOP Senate nominee and effectively pick the next governor of North Dakota.

In South Carolina, Rep. Nancy Mace's Trumpian pivot didn't cost her, as she handily fended off an establishment-aligned primary challenger. Fellow incumbent Rep. William Timmons, who was looking vulnerable after an infidelity scandal, also came out ahead in a closer race against his right-wing challenger. In North Dakota's At-Large Congressional District, Julie Fedorchak became the first non-incumbent woman this cycle to win a GOP primary for a safely red seat. In Nevada, Republican voters chose Sam Brown as their candidate to challenge incumbent Democratic Sen. Jacky Rosen this fall.

Finally, a special election is set to give House Republicans one more seat of breathing room, as voters in Ohio's 6th District filled the seat vacated by Rep. Bill Johnson's departure in January — though not without some unexpected suspense.

As usual, 538 reporters and contributors broke down the election results as they came in with live updates, analysis and commentary. Read our full live blog below.

We've got early results in the GOP race to replace Duncan in South Carolina's 3rd District

With 18 percent of expected vote counted, Air National Guard Lt. Col. Sheri Biggs has a narrow lead with 30 percent of the vote, ahead of pastor Mark Burns and state Rep. Stewart Jones, who are currently at 28 percent and almost 20 percent, respectively. This is not altogether unsurprising, given there was not a ton of daylight between these candidates as far as their political leanings. Burns does have Trump’s endorsement, but Jones has been representing part of the region in the state legislature since 2019, and Biggs has a fundraising advantage. It could very well go to a runoff, but we’ll see if Biggs can grow her lead, or if one of the others takes the lead.

South Carolina GOP state senators who voted against abortion bans are in tough renomination fights

Three Republican state senators in South Carolina are facing tough primary challenges after they voted against abortion bans in the state. Katrina Shealy from the 23rd district, Penry Gustafson from the 27th, and Sandy Senn from the 41st all filibustered to block a total abortion ban in April, and all three drew primary challenges. While there's no votes in yet for Shealy's district, the votes reported so far in the other two districts suggest tough races. With 11 percent of the expected vote reported, Gustafson is currently losing to Lancaster County Councilman Allen Blackmon by a whopping 71 percentage points. In the 41st, with 17 percent of the expected vote reported, Senn is ahead of state Rep. Matt Leber by just 2 percentage points.

Statewide, however, the focus on abortion may not help Republicans in November. According to May polling from Winthrop University, South Carolina voters oppose a 6 week abortion ban by 17 percentage points, 31-48.

Rulli on the ropes?

And remember, Nathaniel, Rulli was the more moderate of the two GOP candidates vying to replace former Rep. Bill Johnson in Congress. His opponent, state Rep. Reggie Stoltzfus, attacked him for his position on gay rights and made a big deal over his past as a "self proclaimed raging liberal" in the 1990s.

The Republican primary in North Dakota will likely pick the state's next governor

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.
