Trump Looms Over Wisconsin Republicans’ Annual Convention

The Republican Party of Wisconsin’s annual convention this weekend in the Wisconsin Dells has a heavyweight figure looming over the conversation, and it’s not the professional wrestling executive turned Cabinet official giving the keynote address.

President Donald Trump demonstrated last week how he still has a chokehold over state-level GOP politics, helping oust five Indiana Senate incumbents who defied his call to gerrymander that state’s congressional districts to help Republicans in the November election.

“He still has a very strong influence on the voting population,” said Jack Hoogendyk, the chair of the Republican Party of Marathon County. “I think what Republicans like about Donald Trump is that he’s not afraid to say what he believes. He doesn’t back down. He just calls all the shots and then he follows through on what he says. I think it’s a good lesson for really any politician regardless of their party.”

Trump’s approval rating has dropped to 42% among registered voters in Wisconsin, but among Republicans it’s 84%. That’s despite Trump’s cataclysmic drag on the party going back to the 2018 midterms, when Democrats won all statewide offices and have since claimed five of seven seats on the Wisconsin Supreme Court.

Ahead of the upcoming state convention, where Education Secretary Linda McMahon will be the featured speaker, Wisconsin Watch talked with four county Republican chairs about how Trump remains a significant factor in their communities ahead of November. It will be up to them to turn out Trump voters in a year when the president’s name is not on the ballot in Wisconsin, they said.

“The conflict with Iran, the issues going on overseas, the affordability, these are huge issues. People have to remember that there’s an entire Cabinet of people and departments that are working on so many other things. So just because these big issues are taking up much of the news cycle, that doesn’t mean that the rest of the work is stopped,” said Hilario Deleon, the chair of the Milwaukee County Republican Party. “The Department of Agriculture, the Department of HHS, the Department of Homeland Security, the FBI, all these different groups are working in conjunction with the vision that the president ran on, and ultimately, he is getting the job done.”

Chad Kinsella, an associate professor of political science at Ball State University in Muncie, Indiana, said the lessons from Indiana primary results can differ for states where election margins are far narrower than deep red Indiana. Trump won that state in 2024 by nearly 20 percentage points, while eking out a less than 1-point win in Wisconsin.

But there’s no question the influence Trump has over Republican voters, Kinsella said.

“He is the 1,200-pound elephant in the room,” he said. “President is … was, and will be for the foreseeable future what … a lot of what people will think about as they vote.”

In Wisconsin, Trump’s endorsement in January of U.S. Rep. Tom Tiffany in the governor’s race cleared the field of major candidates in the Republican primary. Meanwhile, a slew of Democratic candidates continue to seek the party’s nomination ahead of the primary in August.

Fond du Lac County District Attorney Eric Toney also has no primary opponents as he seeks a rematch against Democratic Attorney General Josh Kaul.

“The good thing for us, I think, is we don’t have a contested primary right now for those two top seats. I think that’s very helpful to us,” said Stephanie Soucek, the chair of the Republican Party of Door County. “I think we’ll be able to unify a lot sooner than we typically would be and I think that benefits us. I think just focusing on Wisconsin and what those races are about for our state, I think that will help us.”

Turning out Trump voters

Among self-identified Republican voters in Wisconsin, 40% strongly approve of the job Trump is doing, according to the Marquette University Law School Poll. That’s down from 54% a year ago. County party chairs told Wisconsin Watch that Republicans need to motivate those die-hard fans to participate in elections in a year when Trump is not on the ballot.

“I think we need to find a way to tap into the people who strongly support him, that vote for him,” Soucek said. “And then they need to understand just the importance of electing people that will support his agenda.”

Jerry Helmer, the chair of the Republican Party of Sauk County, agreed that it’s up to county parties to educate voters in their community about Republican candidates beyond Trump. Sauk County Republicans have worked on boosting education and party membership through holding regular Saturday coffee and conservative conversation gatherings at the county party’s office inside an old bank building in Rock Springs, Helmer said.

“We truly feel that there are a lot more Republicans in Wisconsin than show up to vote,” Helmer said. “It was very obvious during the Trump election this last time, they did show up. Part of the problem was education. I worked the polls and I talked to many other people who worked the polls, and so many people only voted for Donald Trump and didn’t vote down ballot.”

Wisconsin Republican leadership debate

The party also has faced a reckoning after conservative Supreme Court candidate Maria Lazar lost the April election by 20 percentage points to liberal justice-elect Chris Taylor.

The results renewed calls for Republican Party of Wisconsin chair Brian Schimming’s ouster as executive committee members told reporters they signed nondisclosure agreements that banned them from sharing closed-door party discussions about the party’s leadership.

WisPolitics reported Friday that the state party canceled an executive committee meeting on May 12 that members sought to discuss “potential action regarding employment issues and board management.”

Neither Schimming nor a spokesperson for the Republican Party of Wisconsin responded to multiple requests for an interview with Schimming for this story.
