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.
Latest headlines:
Is Brown a good candidate?
I'm not yet sold on Brown being a better than average Senate candidate. I think he's done a good job of staying under the radar relative to other GOP nominees in Montana, Ohio, Pennsylvania and Arizona, and avoided some of the missteps those candidates have made. (It doesn't hurt that Nevada is the perpetual redheaded stepchild of the Senate battlefield, always there but never paid much attention.) But he's still relatively untested. His political record includes failed bids for Texas state House a decade ago and for Senate two years ago. If he does ultimately win, I think it has a lot more to do with Trump's performance in the state than Brown's special strength.

Is Rosen vulnerable in November?
Nathaniel mentioned that Rosen's senate seat could be the GOP's best pick-up opportunity outside the Big Three red states (West Virginia, Montana and Ohio). I think that's right. Brown doesn't seem to have any strange local scandals (unlike Sheehy in Montana, for instance)>, so the Nevada GOP didn't Dr. Oz itself here. Although Brown isn't originally from Nevada, he has a compelling personal story as a combat veteran, who suffered third-degree burns from a 2008 roadside bomb explosion in Afghanistan.
Of course, Nevada Democrats have dug up a few possible scandals and will focus on the abortion issue. On his website, Brown mentions that he is personally pro-life, but would not support national abortion ban because it would overturn the decision of Nevadans, so he's trying to thread that needle. Brown's wife has also been telling her abortion story so the Brown campaign must recognize that this will be a salient issue.

Results in Nevada show Trump might get a sweep tonight on endorsements
In the 11 races where Trump has endorsed a candidate, eight of Trump’s picks have won, including Sam Brown in the Nevada Senate GOP primary. One of the former president’s endorsees is going to a runoff, and the remaining two — including John Lee in Nevada’s 4th District — are leading their races. This adds to Trump’s, as he put it recently, “very unblemished” track record. So far this primary season, only one of Trump’s picks for congressional or gubernatorial races has lost (Christine Serrano Glassner, whom Trump endorsed for the GOP Senate primary in New Jersey), so tonight may very well continue that trend.

Lee leading, Flippo following
In Nevada's 4th District, former North Las Vegas Mayor John Lee is leading the GOP primary, 51 to 42 percent, over Air Force veteran David Flippo, with a little less than half the expected vote counted. Lee, a former Democrat, has an endorsement from Trump. Either would be an underdog against Horsford, who weathered targeted races in 2020 and 2022.

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.
