On a cold night in November, a man names jefferson Davis addressed a crowd of conservative activists gathered in an American Legion hall 20 miles north of Milwaukee. In his left hand, Davis brandished an unusual prop.

"In this diaper box are all the receipts for the illegal absentee ballots that were put into the Mark Zuckerberg drop boxes all over the state of Wisconsin," said Davis.

Behind him, a long table stacked with papers, binders and a small pile of doorknobs stretched across the hall. They were for theatrical effect: the doorknobs were a tortured analogy for the multiple conspiracy theories Davis had floated, and the diaper box was a visual stand-in for the ballot drop boxes Wisconsin voters used across the state in 2020. The paperwork, Davis insisted, contained the evidence of an enormous plot to steal the 2020 presidential election from Donald Trump in Wisconsin. His audience of more than 70 people, including local and state-level elected officials, sat rapt.

Davis was speaking at an event organized by Patriots of Ozaukee County, a rightwing group that vows to "combat the forces that threaten our safety, prosperity and freedoms" and compares itself to the musket-toting Minutemen of the revolutionary war.

The organization is one of more than 30 such "patriot" groups in Wisconsin identified by the Guardian which claim that the last presidential election was stolen from Donald Trump. Many, including the Ozaukee county organization, openly embrace Christian nationalist rhetoric and ideology, arguing that the laws of the US government should reflect conservative Christian beliefs about issues like abortion and LGBTQ+ rights.

Their religious interpretation of the US's founding has propelled these groups not only into fights over elections administration but also against vaccine requirements and protections for transgender people.

Now, with the 2024 presidential election less than a year away, Wisconsin's patriot movement and its allies are fighting for legislation that they believe will protect the state's electoral process from fraud, and mobilizing supporters to work the polls, observe polling places and spread the word about their concerns - pushing the GOP further to the right and threatening more challenges to the voting process come election day.

Patriots of Ozaukee County was created in March 2021 by local activists who were "upset about the election", said Scott Rishel, who founded the group. He felt there was nowhere he could speak freely about the 2020 election, or things like Covid-19 vaccines and masks. Plus, he said: "We were tired of the GOP, because they're not really an activist organization."

At the urging of a friend, he convened the group's first meeting.

"With the 2020 election and Covid tyranny, that all opened my eyes," he told the crowd of mostly older couples at the November event. "The silent majority was killing us. It was killing our country, killing our community. And we needed to learn how to no longer be silent."

By "we", Rishel meant conservative Christians. "Jesus Christ is my savior, my lord. It's amazing how some people didn't have the courage to say that - they think it'll make people uncomfortable."

Their movement of biblically motivated patriots has since roared to life, winning some powerful allies along the way.

In attendance at the Ozaukee county meeting was the state senator Duey Stroebel, the vice-chair of the state's powerful joint committee on finance. Stroebel, who has refrained from actually endorsing Trump's false claims that the 2020 election was stolen, has nonetheless backed numerous bills to restrict voting access, invoking the heightened anxiety on the right about election security to justify their passage.

Nearly two hours into the meeting, Stroebel interjected. "One thing you might want to comment on is ranked-choice voting," he said, voicing his opposition to a bipartisan effort in the legislature to adopt the voting method used in states including Maine and Alaska that allows voters to rank their preference on multiple candidates. The method ensures the winning candidate wins a majority rather than a plurality of the vote and essentially eliminates the risk of third-party candidates spoiling an election result.

"Senator Stroebel is referring to what's called ranked-choice voting," Davis told the crowd. "What I call it is ‘guarantee that Democrats win'."

To members of this movement, this proposal is just the latest suspicious attempt to change the voting system to steal elections.

Hardline conservatives have grown increasingly convinced that the election system is rigged against them, largely because Trump has pushed those claims hard since the 2020 election. And in spite of the fact that there was no evidence of significant voter fraud in recent American elections, it has also mobilized local groups into action across the US.

Amy Cooter, a Middlebury College professor whose research focuses on militias and local rightwing groups, described the rise of patriot groups across the country as "a backlash movement". After 2020, said Cooter, local rightwing groups have been motivated largely by "the last presidential election and thoughts that it was stolen - plus concerns that future elections might similarly be".

The patriot movement in Wisconsin appears to be growing. Attendees at November's meeting were unsurprised by the packed house: closer to 200 had attended the Ozaukee group's last event in October, which featured a long lineup of speakers including Davis.

Patriot groups in Wisconsin have found an awkward alliance with Republican officials and prominent activists in the state. A July gathering hosted by the Barron county Republican party, located across the state in north-west Wisconsin, drew closer to 500. That event, which included free beer and a gun raffle and was promoted by patriot groups, illustrated the common cause the movement's activists have found with the grassroots of the GOP.

The Brown county Republican party - also in the north-west of the state - has hosted Constitution Alive! events, which patriot organizations advertised broadly. (A spokesperson said the local GOP is formally unaffiliated with patriot groups.)

"As you know, I travel the whole state," Davis told me in December. "And everywhere I go, I'm either asked to speak by patriot freedom groups, or Republican party chapters. And most of the time both groups show up."

Many patriot groups in the state are animated by the Christian nationalist viewpoint.

Patriots of Ozaukee County declares on its website that it views as fundamental "truths" that "God is our creator" and "Jesus is our savior". The Ozaukee county group has also hosted Constitution Alive! events touting the claim that the US constitution is a Christian document - led by the Patriot Academy organization, a Christian nationalist group that also offers weapons courses.

They're not alone. Patriots United, a group in Eau Claire, Wisconsin, exemplifies the typical rhetoric of the Christian right, describing its membership as "constitutional conservative Christians who seek to glorify and honor God" with the explicit aim of increasing "Christian influence" in local government.

Another Wisconsin patriot group called North of 29 has begun to put into action the work that Davis advocates. With the help of groups affiliated with Mike Lindell, the MyPillow CEO and conspiracy theorist, the group has begun canvassing neighborhoods for voter fraud, using data that they refuse to share publicly to identify instances of suspicious activity. (A similar group in Colorado has been sued in federal court for allegedly going "door-to-door around Colorado to intimidate voters", a practice the suit argues violates the Ku Klux Klan Act.)

Most prominent elected Wisconsin Republicans have refused to outright endorse Trump's claims that the 2020 election was stolen. But they have invoked the fears of election fraud to justify passing restrictive voting legislation that election-denying activists have clamored for.

One bill, passed by the legislature and vetoed by the Democratic governor, Tony Evers, in 2022, would have made it harder for people to qualify as "indefinitely confined", a status disabled voters can claim to receive an absentee ballot. During the 2020 election, during the peak of the Covid pandemic, the number of people who described themselves as indefinitely confined so they could vote from home increased dramatically - a fact that became a central point in conspiracy theories about the election. They've also tried to ban the use of private grants to help fund elections, keying off another conspiracy theory driven by money donated by Mark Zuckerberg's foundation to local offices for election administration; Evers vetoed a bill to ban such money, but the legislature has now advanced the ban as a constitutional amendment which will be considered by voters this spring.

Republicans in the legislature also unsuccessfully tried to force out Meagan Wolfe, the state's nonpartisan top elections official who became the target of conspiracy theorists and election deniers after 2020.

During his November presentation in Grafton, Davis handed out a pamphlet listing 53 issues that voters concerned about election security should focus on in Wisconsin. The priorities, which Davis and other election-denying groups across in the state have embraced, range from abolishing the bipartisan Wisconsin elections commission to requiring ballots cast in state and local elections to be counted by hand.

Davis's recommendations might prescribe technical changes to elections administration. But he cast their importance in starkly biblical terms.

"I don't know where you are with the Lord, and I mean this sincerely: you better pray," said Davis. If the 2024 election wasn't conducted "the correct way", he warned, "there's going to be you-know-what to pay."
