Cory Tomczyk, who hosted the Mosinee rally on the grounds of his industrial recycling company — which provides raw materials to companies making paper products — said he hoped the protests served as a conservative resistance in the same way that the state’s liberals were galvanized by Gov. Scott Walker’s 2011 move to end collective bargaining rights for the state’s public employees.

“People have this image in their head that they’re going to make it look like the protest for Act 10,” Mr. Tomczyk said, referring to the uprising against Mr. Walker’s labor law. “I don’t know if it will look like that, but I hope it will.”

With Ms. McKenna and others in the state’s powerful network of conservative talk radio hosts promoting the rally daily, the event will likely draw scores of Republican elected officials on hand to lend their support, but perhaps not dominating the stage.

Shae Sortwell, a Republican state representative from Manitowoc County, said his caucus’s G.O.P. leadership suggested members not speak at the rally to try to make sure it comes across as “a citizen-led effort.” Mr. Sortwell said he had no qualms about attending the rally.

“Do we want to take away what people have to live for in the sole pursuit of one singular goal of additional survival,” Mr. Sortwell said. “Is it safe, is it unsafe? I don’t know.”

Adrianne Melby, a social media marketer for a Racine County chiropractic firm who is one of the planners of the Madison rally, said organizers had sought to portray the event as homegrown and apolitical. She said they turned down a donor’s offer to help pay for the event, though Ms. Melby declined to say who made the offer.

Wisconsin’s State Capitol Police on Monday denied the Madison group’s official permit request. Mr. Evers’s spokeswoman, Melissa Baldauff, said there would not be an effort to stop people from gathering outside the Capitol — they just would not be allowed inside the building.
