Jenkins swept the Greater Monvaille area, winning large margins that his two opponents could not overcome.
At the same time, he also won many rural counties.
State Sen. Bill Passaneas, who was the front-runner and who entered the race almost two years ago, conceded to Jenkins Monday night.
The two men held election night celebrations just across town in the suburbs south of Monvaille, where they both hail from.
"Congratulations to DeMerius. It's clear he has the passion, and he has captured the attention and the favor of Lial's NAT voters. I wish him a successful campaign this fall," said Passaneas.
Lial Attorney General Alice Mobley, who finished last in the three-way race, also conceded at her celebration further downstate in Bambois.
"I want to wish DeMerius the very best as he moves on to the fall election, and to the very tough challenge of taking on Junes Charmagne. I hope our party can come together and unite, because when we are united, we are unstoppable," she said to a group of her supporters, who gathered at a wine bar in the small city where she grew up.
Lial Gov. Junes Charmagne (C), who is seeking an unprecedented third term this fall, also congratulated Jenkins.
"Congrats to @DeMerius Jenkins on his big win. I look forward to debating the issues and sharing our very different visions for the state of Lial in the coming months," wrote Charmagne on his X account, formerly Twitter.
Initial returns from rural counties showed Passaneas firmly in the lead. But as more ballots came in from Monvaille and its suburbs, it was clear Jenkins had the momentum.
At just age 39, he is the youngest nominee for governor in Lial history, as well as the first person of color.
Then a little-known state representative from Monvaille's south side, Jenkins first made a name for himself in 2022, when he narrowly defeated Conservative Lieutenant Governor Jim Fallberry.
That race hinged greatly on race, crime and policing.
Jenkins has used his campaign for governor to highlight those same issues.
Conservatives have already pounced on comments he made about abolishing immigration enforcement, reducing police forces, and reducing funding for police.
"DeMerius Jenkins really is the dream candidate for Conservatives. He is a self-described socialist who wants less police and more government ownership of private property. He wants to take away people's money and 'spread the wealth' to the masses. All hard-working Lialans are going to see right through his crazy policies and vote for someone who understands economics, the free market, and letting people keep their money," said Curtis Scholer, a Conservative strategist who works in Lial politics, but who is not involved in the race.
Charmagne has enjoyed high popularity as Lial's economy has boomed, with increases in manufacturing jobs and investment from foreign companies.
The moderate CNS governor, who is socially liberal, has championed low taxes, a business-friendly agenda, and has personally made multiple trips around the world to recruit major companies to Lial.
Charmagne has also advocated for more police and a tougher stance on crime, though he has largely left local policing matters to local authorities.
In his third term, should he win one, Charmagne has expressed his desire to crack down harder on the city of Monvaille, whose liberal leaders have often thumbed their nose at the governor.
Charmagne says that while the state's economy has boomed as a whole, Monvaille's economy continues to "drift," as the "liberal politicians" who run the city have opposed his "growth-driven policies."
"Crime and homelessness continue to be out of control in Monvaille," said the governor at a press conference last week. "I've tried to work with the mayor, the city council, and all those folks. They have opposed me at every turn, simply because of politics. They are actually willing to sell their city down the river and let their city drown in crime and homelessness, just because they don't want to work with Conservatives. It's sad. It's wrong. It's unconscionable. But these are the radical left lunatics we're dealing with," he said, using similar language to US President Donald Trump.
Jenkins disputed that characterization of his home city, telling his supporters on primary election night that "Monvaille is thriving, despite what Junes Charmagne and the Conservative fear-mongers say."
"When I see Monvaille, I see a city that is alive, with culture, with diversity, with art and love. Don't believe what you hear on right-wing news channels and social media. Monvaille is doing great."
Still, the lieutenant governor said the state's largest city, which is also the nation's third-largest city, is too expensive, and many Monvailleans are struggling to afford urban life.
"We still have too many people who can't afford rent, who can't afford their medical bills, who can't afford groceries. We have work to do, and we're going to make life more affordable for Lialans," said Jenkins.
He has supported popular democratic-socialist policies, such as allowing the City of Monvaille to purchase and run grocery stores to lower prices for citizens. And providing free public transportation for all Monvailleans.
Conservatives call those ideas "radical" and "bound to fail," and say Lialans will choose "common sense" this fall.
"These pie-in-the-sky socialist policies of DeMerius Jenkins and the Nationalists, they just don't work. We've tried socialism before. We've seen it in effect in other countries. And not once has it ever succeeded. It won't succeed here either, but I hope we don't even give them the chance to try it," said Conservative strategist Evan Modick.
Polls conducted on the Lial governor's race show Charmagne comfortably in the lead. However, Nationalists are hoping economically distressed voters in Monvaille's urban core will grow tired of the incumbent governor and be ready for change.
"DeMerius Jenkins represents change on so many levels. Not just a change in policy, but a change in generations, a change in viewpoints on how the economy should work for everyone, and a change in the lease of equity," said Sean Aston, a Monvaille-based Nationalist political operative who worked for the Mobley campaign.
Ultimately, the fate of the race may come down to the suburbs of Monvaille, which are notorious swing territories.
Smaller cities such as Castleton, Kappasanna, Cedrickson, Sauvienne, Naving, Bambois and Brisanten may also play a significant role in the race.
Dr. Kerry Rudgley, of Dulkalow University, currently rates the Lial governor's race as "Conservative Favored."
