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.

Timmons has taken the lead in South Carolina's 4th District

With 31 percent of the expected votes counted, incumbent Timmons has now taken the lead in South Carolina's 4th District. He currently has 54 percent of the vote to Morgan's 46 percent. Election day voters tend to be more conservative, but this is a district that is already the most conservative in the state, having gone for Trump 68 percent in 2020, so that’s slightly less of a factor here, and Timmons may have overcome that early surge from Morgan.

Election day votes are coming to Republicans' rescue in Ohio

Counties are beginning to count their election day votes in Ohio’s 6th District special election, and as expected, they’re really good for Rulli. With 29 percent of the expected vote counted according to the AP, Kripchak’s lead is down to 54 percent to 46 percent.

Mace still ahead in South Carolina's 1st

We’re up to about 20 percent of the expected voted counted and Mace is still ahead of Templeton by a healthy margin, 57 percent to 29 percent. She’s well ahead in Berkeley and Dorchester Counties, which were the two localities to vote against her in her relatively close 2022 GOP primary, so that’s a good sign for her. Still early, but the crush of outside money from the Club for Growth backing Mace seems to have accomplished its mission.

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.

Trump seems likely to pad his primary endorsement record in tonight's races

As usual, tonight we'll be watching to see how candidates endorsed by Trump fare in their respective races. The former president loves to tout his "very unblemished" track record for endorsing candidates who win, though when you take a closer look at his numbers, it's not always that impressive. Still, Trump's seal of approval can often be enough to give an edge in a tight primary race, so we'll be watching the 11 races tonight where he has endorsed a candidate:

Trump has already won in two of today's races, since he endorsed incumbents North Dakota Sen. Kevin Cramer and South Carolina Rep. Russell Fry, each of whom are running unopposed. He'll also likely have luck with the other two incumbents he endorsed, Reps. Nancy Mace and William Timmons in South Carolina, though they're facing challengers. As for non-incumbents, Trump made a last-minute endorsement of retired U.S. Army Capt. Sam Brown, who's enjoyed strong party backing and is heavily favored to win. His pick in Maine's 2nd District, former NASCAR driver state Rep. Austin Theriault, also seems to be favored to win, as does former North Las Vegas Mayor John Lee in Nevada's 4th District.

But Trump has had a few disappointments in recent weeks. Mendham Mayor Christine Serrano Glassner, whom Trump endorsed for the GOP Senate primary in New Jersey, lost by 7 percentage points last week, and his endorsee for Texas's 21st State House District narrowly lost his primary in a May 28 runoff. I'll be keeping an eye on these races as results come in tonight, and will keep you updated on how blemished or unblemished Trump's record remains.
