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.

Will Biggs even stay in the race for the runoff?

As Meredith has noted, Biggs is one of the House GOP’s best chances yet to add a new woman to their caucus. However, I wonder if she will even stay in the race for the June 25 runoff. As David Bernstein notes on BlueSky, twice so far this year (in North Carolina’s 6th and 13th), a Republican candidate has made it to a runoff against a candidate endorsed by Trump only to drop out of the race because they faced such low odds of winning.

It's a runoff in South Carolina's 3rd!

The AP is projecting the GOP race to replace retiring Rep. Jeff Duncan in South Carolina's 3rd District will go to a runoff, with pastor Mark Burns and Air National Guard Lt. Col. Sheri Biggs squaring off. With 85 percent of the expected votes counted, Burns currently leads with 32 percent of the vote, with Biggs tailing him with 29 percent of the vote. With those margins, it's anyone's race in two weeks!

Armstrong projected to win Republican gubernatorial primary

With 20 percent of the expected vote in, the Associated Press is projecting that Armstrong will win the North Dakota Republican gubernatorial primary, with 67 percent of the vote so far, compared to Miller's 33 percent. It's a quick result for such a contentious race, where the candidates shared many agreements over policy. Armstrong is likely to triumph over Piepkorn in November in this very red state (although we don't know who would win a singing contest.)

Fedorchak opens up an early lead in North Dakota

Only about 17 percent of the expected vote is in for North Dakota's At-Large Congressional District Republican primary, but the Trump- and Burgum-endorsed Fedorchak has opened up an early lead with about 44 percent of the vote so far, according to the AP compared to Becker's 31 percent. As Geoffrey noted in his race preview, a third candidate, Balasz, technically has the endorsement of the state GOP due to a rebellion by Becker supporters upset that he was ineligible for endorsement; Balasz only has about 5 percent of the vote so far.

The GOP primary in South Carolina's 3rd District could head to a June 25 runoff

The strongly Republican 3rd District in Upstate South Carolina features an open-seat race following the retirement of Republican Rep. Jeff Duncan, who also faced accusations of marital infidelity. In the GOP primary to succeed Duncan, the most notable contenders appear to be pastor Mark Burns, Air National Guard Lt. Col. Sheri Biggs and state Rep. Stewart Jones, but it's difficult to identify a favorite. On the fundraising front, Biggs had raised $528,000 as of May 22, while Burns had brought in $516,000, both largely through self-funding. Jones, meanwhile, had raised $217,000 with less self-funding, having represented a part of this region in the state legislature since 2019.

Outside spending here has come principally via the Sen. Rand Paul-associated Protect Freedom PAC's $670,000 outlay to help Jones and Elect Principled Veterans Fund's $314,000 to support Biggs. But it's Burns who has garnered Trump's critical endorsement. Burns's political profile as a pro-Trump Black televangelist has grown in recent years, including a second-place finish in the 4th District's 2022 primary.

But Burns has attracted controversy, too, including in 2016 when he retweeted a fake photo of Hillary Clinton in blackface, and in 2022 when he called for the execution and arrest of those who support protecting transgender children. For her part, Biggs has the support of Republican Gov. Henry McMaster, while Jones gained notice for his efforts to dismantle COVID-19 pandemic-related restrictions. A runoff seems like a real possibility: The only public poll was a mid-May survey by Cygnal on behalf of the pro-Biggs Elect Principled Veterans Fund, which found all three contenders hovering around 10 percent.
