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.

Polls are now closed in Maine and most of North Dakota

It's 8 p.m. Eastern, and polls are now closed in Maine and most counties in North Dakota. (Voting hours in the Peace Garden State vary by municipality, with polls largely closing at either 8 p.m. or 9 p.m. Eastern.) We'll be bringing you results from races in both these states shortly.

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.

That’s a wrap!

Well, it’s unclear when we’re going to know the winners in the last few Nevada races, so we’re going to call it a night. Here’s a roundup of what happened in June 11’s key races:

- In the special election in Ohio’s 6th District, Republican state Sen. Michael Rulli defeated Democratic Air Force veteran Michael Kripchak, but by a shockingly narrow margin (9 points). Trump won this district by 29 points, so Democratic enthusiasm was really high here.
- In South Carolina’s 1st District, Republican Rep. Nancy Mace survived her second straight contested GOP primary as an incumbent, and by a much more comfortable margin than two years ago. Mace will face businessman Michael Moore (no, not that one) in the general election, where she’ll be the heavy favorite.
- In South Carolina’s 3rd District, the Republican primary is going to a runoff, with the top two candidates — Trump-endorsed pastor Mark Burns and Air National Guard Lt. Col. Sheri Biggs, who finished neck-and-neck — facing off again in two weeks.
- In South Carolina’s 4th District, Rep. William Timmons barely beat back a strong primary challenge from tea party Republican state Rep. Adam Morgan.
- Up north in Maine’s 2nd District, former NASCAR driver and current state Rep. Austin Theriault easily clinched the GOP nomination over his colleague Michael Soboleski. Now Theriault will race against Democrat Jared Golden, the Blue Dog who’s held this seat since 2018.
- In North Dakota, the Republican primary for governor was projected early, with Rep. Kelly Armstrong pulling quickly ahead of Lt. Gov. Tammy Miller. And the contested GOP primary for the state’s open at-large congressional district was projected for Public Service Commissioner Julie Fedorchak.
- For U.S. Senate in Nevada, Army veteran Sam Brown scored an easy win in the Republican primary. He’ll face Democratic Sen. Jacky Rosen this fall in what will be one of the nation’s most closely watched Senate races.

Finally, here’s the status of the three unprojected races in Nevada.

- Nevada’s 1st District looks like it will be a rematch, with 2022 nominee Mark Robertson leading the Republican primary for the right to once again face incumbent Democratic Rep. Dina Titus. However, Flemming Larsen could still win the GOP nomination too.
- In the crowded Republican primary in Nevada’s 3rd, conservative columnist Drew Johnson has a narrow lead over former state Treasurer Dan Schwartz. "Halo" composer Marty O’Donnell, the establishment pick, is in a surprising third place.
- In Nevada’s 4th, former North Las Vegas Mayor John Lee appears to have the inside track over Air Force veteran David Flippo.
