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.

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.

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.

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.
