“Whether it’s fair or not, they see this all as one monolith: From Biden on down to the guy throwing the brick at the cop,” said Mr. Wigderson, who has been critical of Mr. Trump. “As a result, they are more motivated not to let those people win.”
That was all the more true for committed Republicans in Kenosha. Don Biehn, 62, owner of a flooring company, was standing in line at a gun store on Tuesday afternoon. He said that he had never bought a pistol before, but that he had a business to protect. A former county board supervisor, Mr. Biehn said he had been calling county and state officials for days, trying to explain how grave the situation was.
Neither John Antaramian, the mayor of Kenosha, nor Jim Kreuser, the county executive, responded to requests for comment. (The positions are nonpartisan, but both men previously served in the State Assembly as Democrats.)
“There’s people running all over with guns — it’s like some Wild West town,” Mr. Biehn said. “We are just waiting here like sitting ducks waiting to get picked off.”
He added: “It’s chaos — everybody is afraid.”
Mr. Trump, he said, “was not my man,” but now he is grateful he is president.
He said he seemed to understand in a way that other politicians did not.
“There’s nobody fighting back,” he said. “Nobody is paying attention to what’s going on.”
Scott Haight, who was boarding up a line of businesses in a Kenosha strip mall on Tuesday, said he blamed Lt. Gov. Mandela Barnes, a Democrat, for what he said was irresponsibly stirring up emotion. (On Monday, Mr. Barnes said the shooting “wasn’t an accident.”)
