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.

Republicans will pick their opponent for Nevada Democratic Sen. Jacky Rosen

We're about 20 minutes out from polls closing in Nevada, so let's take a look at some of the key races happening there tonight.

Nevada will hold a pivotal Senate contest this fall for the seat held by Democratic Sen. Jacky Rosen. Retired U.S. Army Capt. Sam Brown is the front-runner in the Republican primary, having established himself by finishing second for the GOP nomination in Nevada's 2022 Senate race. Brown's candidacy is highlighted by his military service record, during which time he suffered third-degree burns from a 2008 roadside bomb explosion in Afghanistan. Brown has proved a prodigious fundraiser, having brought in $7.1 million as of May 22. Former Ambassador to Iceland Jeffrey Ross Gunter, who served under Trump, is Brown's main competition, and he's self-funded $2.7 million of the $3.3 million he's raised.

National Republicans have largely consolidated behind Brown, including the National Republican Senatorial Committee. Brown and the NRSC have run joint ads focused on immigration and national security, and Rosen's campaign is already running spots against him focused on abortion rights. For his part, Gunter has linked himself to Trump, though Trump made a last-minute endorsement of Brown Sunday night, and has run ads claiming Brown backs the controversial-but-stalled plan to store nuclear waste at Yucca Mountain. Brown expressed support for the plan during his 2022 bid, but has backtracked in the face of criticism this time around.

It's unclear how big a threat Gunter is to Brown, as an early June survey from Noble Predictive Insights found Brown ahead 53 percent to 15 percent. But Gunter released a late May survey by Kaplan Strategies that found him running about even with Brown at around 30 percent. Outside groups have come in big for Brown to the tune of $4.3 million, and Gunter is enough of a danger that the pro-Brown Duty First Nevada super PAC is running ads portraying Gunter as a fake Republican. Still, Gunter's campaign actually canceled some ad buys ahead of the primary — not exactly a signal of confidence.
