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.

North Dakota Congressional age limit measure is projected to pass

According to the AP, the Congressional age limit ballot measure in North Dakota is projected to pass. With 70 percent of the expected vote reported, support for the measure is at 61 percent. As I mentioned earlier, this makes North Dakota the first state in the nation to enact such a law, but it undoubtedly will face legal challenges in the coming years.

Speaking of anti-abortion Republicans in South Carolina ...

I checked back in on the three "sister senators" in the state Senate I mentioned earlier, who banded together to successfully filibuster against a near-total abortion ban in the state. According to the AP, Gustafson is projected to lose renomination in the state's 27th to Blackmon. In the 23rd, Shealy is 4 percentage points ahead of Carlisle Kennedy with 88 percent of the expected vote reporting. But with Shealy holding only 40 percent of the vote so far, that race looks to be heading to a runoff. And in the state's 41st, we've got quite the nail-biter: With 80 percent of the expected vote reporting, Senn is behind Leber by just 0.4 points. All together, it looks like all three women are in danger of losing their seats to anti-abortion male challengers.

Checking in on anti-abortion candidates in South Carolina

Biggs was one of the anti-abortion candidates we were watching tonight, and her advance to a runoff in the 3rd district primary against Burns gives her something like a win — though as others have noted, she's an underdog in that contest. Templeton lost to Mace in the 1st district, while incumbent Timmons is solidly leading in his primary in the 4th district, according to the AP. With 56 percent of the vote so far and nearly three-fourths of the expected vote reporting, AP projects that Buckner will win his 6th District primary.

The AP is projecting that Fedorchak will win the Republican primary in North Dakota's at-large congressional district race. With 72 percent of the expected vote reporting, she has 46 percent of the vote so far. Her nearest challenger, Becker, has 29 percent of the vote so far.

GOP Rep. William Timmons tries to overcome scandal in South Carolina's 4th District

In the solidly red 4th District around Greenville, third-term Rep. William Timmons is another Republican incumbent dealing with a high-profile primary challenger. Though Timmons is a reliable conservative, state Rep. Adam Morgan could successfully run even further to Timmons's right, seeing as he chairs the state House's Freedom Caucus — modeled after the congressional caucus, whose membership encouraged Morgan's bid and whose campaign arm has endorsed him. Moreover, Timmons still seems to be plagued by a scandal that jeopardized his reelection bid two years ago: In 2022, amid allegations that Timmons was unfaithful to his wife, he only won renomination with 53 percent against weak primary opposition.

One sign that Timmons is feeling the heat is that he's done something unusual in a GOP primary: He's attacked his opponent for being too extreme on abortion rights, running an ad criticizing Morgan for voting "to jail rape and incest victims" who sought abortions — a vote Morgan has defended as "an attempt to close a loophole." Timmons's maneuver could be an attempt to draw Democratic and independent votes in South Carolina's open primary system, even though the incumbent supports a 15-week federal abortion ban.

Timmons still has some notable advantages working for him. He's outraised Morgan $1.9 million to $578,000, helped out by a $900,000 loan to his campaign (Morgan has self-funded nearly half his campaign, too). Outside groups, mainly the pro-cryptocurrency Defend American Jobs super PAC, have spent $1.9 million to boost Timmons, compared with just $327,000 in outside spending supporting Morgan. And here, too, Trump has endorsed the incumbent, which Timmons and his allies have played up in campaign ads. Still, Morgan has emphasized his Republican bona fides, pitching himself as a Christian and "conservative fighter" in his ads.
