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.

Checking in on anti-abortion candidates in South Carolina

We're still waiting on results from most states, but I'm tracking early results on anti-abortion candidates in South Carolina. In the 1st Congressional District, Templeton is trailing Mace 29 percent to 57 percent, with 20 percent of the expected vote reporting, according to the AP. In the 3rd District, the AP is reporting that Biggs is now barely trailing in second place with 30 percent of the vote, with her nearest competitor, Burns, at 31 percent, and 45 percent of the expected vote reporting. Morgan is slightly ahead of incumbent Timmons in the 4th District, 52 to 48 percent (with 16 percent of the expected vote reporting), while Buckner is ahead of Scott in the 6th District 56 to 44 percent, with 21 percent of the expected vote reporting. The other two Republican House primaries are uncontested.

A singer, a cowboy and now a nominee

In North Dakota, where most polls have closed, the Democratic gubernatorial nominee is Merrill Piepkorn, a state senator and radio host who's also a bit of a singer. You can check him out on YouTube. (And he probably won't win his race this year against either Armstrong or Miller, so he has plenty of time to keep serenading us all.)

In SC-04, incumbent Timmons is currently behind

With 16 percent of the estimated vote reporting, Republican Rep. William Timmons is currently behind state Rep. Adam Morgan. Morgan currently has 52 percent of the vote to Timmons's 48 percent. Despite Timmons being pretty darn conservative, Morgan, who chairs the state level Freedom Caucus and got the endorsement of the Congressional Freedom Caucus's campaign arm, ran to his right. Timmons has Trump's endorsement, but it might not be enough to keep him from getting bested tonight.

An update in Ohio’s 6th District

Every county in Ohio’s 6th District has now reported what are likely the bulk of its early/absentee votes, and Kripchak leads 61 percent to 39 percent districtwide, with 19 percent of the expected vote reporting. Now we wait and see just how red the Election Day vote is. Again, I expect Rulli to win once all those votes are counted, but he does have a notable deficit to make up.

The winner of Maine's 2nd District GOP primary will face an endangered Democratic incumbent in fall

Maine's 2nd District is host to a GOP primary in which two first-term state representatives, Austin Theriault and Mike Soboleski, are contending for the right to take on three-term Democratic Rep. Jared Golden. The incumbent has managed to hold onto this seat, which takes in most of Maine north of its southern coastal area, despite its slight Republican lean: Trump would have carried it 51 percent to 45 percent in 2020, according to Daily Kos Elections, making it the second-most Republican-leaning seat (by presidential vote) that a Democratic incumbent is defending in 2024, trailing only Rep. Mary Peltola's at-large seat in Alaska.

Theriault, a former NASCAR driver, looks to be favored. He has Trump's endorsement, which he's naturally emphasized in his ads, and he's congressional Republicans' top choice, having earned the backing of Speaker Mike Johnson and the Congressional Leadership Fund. Moreover, Theriault has raised $1.2 million to Soboleski's $117,000. The only somewhat recent poll was an early April survey from Public Opinion Strategies on behalf of Theriault's campaign that found him leading Soboleski 30 percent to 7 percent. But while Theriault has Trump's backing, Soboleski aligns with the former president — and around two-thirds of Republicans nationally — on the question of the 2020 election's legitimacy. Unlike Theriault, Soboleski has echoed Trump's unsupported claim that Biden didn't legitimately win.
