It's 7:30 p.m. Eastern, which means polls are now closed in Ohio. There are no primaries in the Buckeye State tonight, but there is a special election in the state's 6th District, which was represented by Republican Rep. Bill Johnson until January, when he resigned to lead Youngstown State University.

According to Daily Kos Elections, Ohio's 6th District voted for Trump 64 percent to 35 percent in 2020, so Republican state Sen. Michael Rulli should easily defeat Democratic Air Force veteran Michael Kripchak there today. However, we'll still be keeping an eye on Rulli's winning margin as an indicator of the national political mood. Special election performance over a partisan baseline has historically been a good predictor of general election outcomes.

That said, individual special elections can be idiosyncratic, so you really need to consider today's result in Ohio's 6th alongside the other special congressional elections we've had this cycle. So far, Democrats have overperformed the weighted partisan leans of the districts in those elections by an average of 4 percentage points. We'll see how much — or whether — Ohio's 6th moves that average.

I don't know about the cinematography, Monica, but if Halo composer and NV-03 candidate Marty O'Donnell comes out on top in his GOP primary tonight, I hope we'll see some great campaign ad scores from him.

… It was one of the few times a public figure claiming to be from a "small town" was legitimately from a small town. Burgum’s hometown, Arthur, North Dakota, has a population of 328 at the 2020 census. That’s even smaller than 538's tiny-town contingent: My hometown population is 506, and Monica’s hometown has a population of 2,500.

One of the races I'm watching tonight is the Republican primary for North Dakota's governor, and, as Geoffrey noted earlier, that race has been increasingly heated. Of course, the Republican nominee is seeking to replace Burgum, who is retiring after a brief run for the Republican nomination for president, and amid chatter that he could be Trump's vice presidential pick. So I'd just like to take a moment to remember this cinematic video Burgum used to launch his presidential campaign, with a voiceover that praised small-town values over scenic images of hills and livestock. Maybe we can look forward to such a video one day from his successor.

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.
