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.

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.

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.
