Strange things can happen in the desert. On Wednesday morning in San Tan Valley, Arizona, I watched Kari Lake, the Republican Senate candidate, come within a few feet of violating a fundamental election law.

Lake’s campaign bus had just rolled up to an early-voting site roughly an hour southeast of Phoenix. Along the path leading to the precinct’s entrance was a yellow sign that read 75 FOOT LIMIT. The post warned that electioneering beyond that threshold would constitute a Class 2 misdemeanor. Lake, as is her proclivity, waltzed right up to the line with a knowing smile.

I stood nearby, watching Lake glad-hand and pose for selfies with voters, who seemed surprised to see her. I heard her ask a man if he’d voted for Donald Trump. Amid the campaigning, she found time to attack the media. When I told her I was reporting for The Atlantic, she replied, “Oh, is that that really, really, really biased outlet?” (Three reallys.) Lake appeared to be performing for the cameras, but at that stop, there were none, save for those of her own campaign. It was just me and three other journalists with notebooks. No matter: This was, after all, Kari Lake. Bombast is her brand.

Lake may be the most MAGA-fied downballot candidate in the country. (The phrase MAKE ARIZONA GRAND AGAIN is splayed across the side of her bus next to a giant image of her head.) A former local-TV news anchor, Lake first gained national attention by promoting Trump’s lies and conspiracy theories about Arizona’s 2020 election results. When she ran for Arizona governor in 2022, she refused to accept her defeat. Most candidates make their name on a particular issue; election denialism, more than anything, has come to define Lake.

Once seen as Trump’s potential 2024 running mate, Lake is now battling the Democrat Ruben Gallego for the Arizona Senate seat soon to be vacated by Kyrsten Sinema. The RealClearPolitics polling average suggests that she could be on the verge of another loss. Trump, meanwhile, appears poised to retake the state at the top of the ticket. Although no outcome is guaranteed, on Tuesday, in a border state plagued by division and extremism, both a Democrat and a Republican might emerge victorious.

Such a result would come as a shock to many. It might particularly rankle conspiracists and those who have spent years casting doubt on the validity of America’s electoral systems. People, in other words, such as Kari Lake.

That morning, she took questions from the three other reporters, but looked at me and said, “I’m not talking to your outlet.” So I instead approached one of her surrogates, Richard Grenell, who served as Trump’s ambassador to Germany and later as the acting director of national intelligence. Grenell, too, had antagonized The Atlantic alongside Lake just minutes before. (Just as Trump did in a recent rally, Grenell claimed without evidence that our editor in chief, Jeffrey Goldberg, had “made up a lot of stuff.”) But now, in a quieter setting off to the side of the scene, he was willing to speak with me.

I informed Grenell that I had planned to ask Lake a straightforward question: Would she commit to accepting next week’s election results? He scoffed at the premise.

“It’s a dumb question to be like, ‘Do you accept the results of an election?’” Grenell told me. He said that “of course” she would accept the outcome if it were a free and fair election. “Let me ask you this question,” he said. “Do you think there’s no fraud in the election? Zero fraud?”

Lake saw me speaking with Grenell, and as she was heading back to her bus, she and I made eye contact. The crowd was smaller now, and Lake was chatting in a slightly dialed-down register. Professional wrestlers have a term to describe the performative antagonization of an opponent: kayfabe. Based on what I had seen of Lake prior to that moment, though, I didn’t think she ever snapped out of her combative persona when dealing with the media. As we briefly spoke one-on-one, Lake wasn’t exactly friendly, but she was at least willing to let me finish a sentence. I asked her if she’d accept the election results.

“A legally run election? Yes, absolutely,” she said. “One hundred percent.”

But how do you define that?

Suddenly her switch flipped. With a bright smile and sarcasm in her voice, Lake said, “I will accept the results of the election, absolutely!” Then she swiftly got back on the bus.

Later that afternoon, I drove to a strip mall in Maryvale, a predominantly Latino neighborhood in metro Phoenix, to meet Gallego, Lake’s challenger. Between a barber shop and a check-cashing place, Arizona Democrats had set up a bustling field office. Inside the room, papel picado banners hung from the drop ceiling, the walls were plastered with posters—Latinos Con Harriz Walz, Democratas Protegen El Aborto—and, on the far side of the room, someone had handwritten a slew of motivational quotes (“If you have an opportunity to make things better and you don’t, then you are wasting your time on Earth.” — Roberto Clemente). When I turned around, I spotted Gallego chatting with that day’s volunteers. He was dressed casually in a short-sleeve button-down and jeans, and he wasn’t surrounded by a large entourage, as Lake had been. He and I found a quiet corner, and I asked him the same question I had asked Lake: Would he commit to accepting the election results? He didn’t hesitate.

“I trust the Arizona election system. I trust the Republicans and Democrats that have been running the state, and I will trust the results of the election, win or lose,” Gallego said.

Right now, the 44-year-old is in a rare position: He knows he stands a chance of winning over Lake-wary Republicans. He’s a Democrat, but, as a former Marine who has spoken out on culture-war issues, such as against the use of Latinx, he may appeal to some centrists and independents as well. Above all, he’s positioned to woo some of the most sought-after persuadable voters in the region: Latinos. He sometimes tells a story about how he grew up sleeping on the floor and didn’t have a bed until he got to college. On the stump, he often delivers remarks in both Spanish and English.

What Gallego is not doing is running a straight Democratic-party-line campaign. When I asked him how he felt about Joe Biden’s comments that Trump supporters are “garbage,” he didn’t rush to unequivocally defend the president. “No matter what, we shouldn’t be castigating people for how they vote,” he said. I also asked him if he anticipated civil unrest next week, given the chaos that had unfolded in Arizona in previous elections. “I really have faith in the voters of Arizona—Democrats, Republicans, and independents—that they’re going to go vote, and they’re going to keep it civil,” Gallego said. “I hope that the politicians would actually keep it civil and not try to bring election denialism into it, like Kari Lake has. That’s where the danger has happened.”

Gallego had stopped by that office to rev up volunteers for a canvassing operation. Joining him was Senator Mark Kelly and his wife, former Representative Gabby Giffords. That afternoon, I asked Kelly what sort of challenges he and his fellow Arizona Democrats were anticipating after Election Day, and whether he believed that Lake (and Trump, for that matter) would accept the election’s outcome. “They should,” Kelly said cautiously. “I mean, I don’t expect their behavior to be much different than it was in the 2020 and 2022 election, though. I mean, I have no reason to expect that. But you know, you can always dream that maybe they’ve learned a lesson,” he said. “Kari Lake certainly should have learned her lesson.”
