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.

We're waiting, Nevada …
It's been almost an hour since polls closed in Nevada, and still no results have been released. Maybe they got stuck in line at the Sphere?

What secrets may Eastern Colorado hold?
I for one am now very curious how the special election in Colorado’s 4th District plays out in two weeks. We’ve been treating it like a solid Republican seat. After all, Trump won it by 19 points in 2020. But in tonight’s Ohio 6 special, the Democrat outperformed Trump’s margin by — wait for it — 19 points. At least very superficially, that’s a reminder that special elections can produce quirky outcomes. In fairness, Colorado’s concurrent regular primary should help boost turnout in the Centennial State, especially with the crowded and high-profile GOP primary in the 4th District that features Rep. Lauren Boebert. But I’m still interested in how Republican Greg Lopez does in the special election and whether Democrats can keep up the strong over-performances they’ve notched so far this cycle.

North Dakota’s Measure 1 seems doomed in court
Mary, you mentioned potential legal challenges for North Dakota’s ballot measure setting congressional age limits. It's pretty clearly unconstitutional under current Supreme Court precedent; the court found in 1995's U.S. Term Limits v. Thornton that states can't impose qualifications to run for office beyond those set forth in the Constitution. (And while the Constitution sets a minimum age to be elected to Congress, it's silent about a maximum.) However, congressional expert Matt Glassman writes on X that this ballot measure could be a way to get the Supreme Court to reconsider that precedent — which could open the door to congressional term limits as well.

Fedorchak's projected win is a milestone for GOP women this cycle
With Fedorchak's projected win in North Dakota’s at-large district, she becomes the first non-incumbent Republican woman to win an open primary in a safe red district this cycle. Why have Republican women had such a slow start in primaries this year? We wrote about some possible explanations last week.

Republicans will pick their opponent for Nevada Democratic Sen. Jacky Rosen
We're about 20 minutes out from polls closing in Nevada, so let's take a look at some of the key races happening there tonight.
Nevada will hold a pivotal Senate contest this fall for the seat held by Democratic Sen. Jacky Rosen. Retired U.S. Army Capt. Sam Brown is the front-runner in the Republican primary, having established himself by finishing second for the GOP nomination in Nevada's 2022 Senate race. Brown's candidacy is highlighted by his military service record, during which time he suffered third-degree burns from a 2008 roadside bomb explosion in Afghanistan. Brown has proved a prodigious fundraiser, having brought in $7.1 million as of May 22. Former Ambassador to Iceland Jeffrey Ross Gunter, who served under Trump, is Brown's main competition, and he's self-funded $2.7 million of the $3.3 million he's raised.
National Republicans have largely consolidated behind Brown, including the National Republican Senatorial Committee. Brown and the NRSC have run joint ads focused on immigration and national security, and Rosen's campaign is already running spots against him focused on abortion rights. For his part, Gunter has linked himself to Trump, though Trump made a last-minute endorsement of Brown Sunday night, and has run ads claiming Brown backs the controversial-but-stalled plan to store nuclear waste at Yucca Mountain. Brown expressed support for the plan during his 2022 bid, but has backtracked in the face of criticism this time around.
It's unclear how big a threat Gunter is to Brown, as an early June survey from Noble Predictive Insights found Brown ahead 53 percent to 15 percent. But Gunter released a late May survey by Kaplan Strategies that found him running about even with Brown at around 30 percent. Outside groups have come in big for Brown to the tune of $4.3 million, and Gunter is enough of a danger that the pro-Brown Duty First Nevada super PAC is running ads portraying Gunter as a fake Republican. Still, Gunter's campaign actually canceled some ad buys ahead of the primary — not exactly a signal of confidence.
