COCHRANE, Wis. — Dozens of calves groaned as Hermenegildo, a young Mexican farmworker, wheeled out a cart with bottles of milk. He attached the bottles to the wood pen of each calf, walking up and down the row as the animals guzzled the milk in minutes. The 600 cows on the dairy farm produce 5,000 gallons a day, which are trucked for processing into cheese at a plant owned by a Minnesota cooperative.
Farm owner John Rosenow credits immigrant labor with sustaining his business, estimating that at least 90% of the workers on Wisconsin dairy farms are unauthorized. He turned to Mexican migrants 25 years ago, he said, when he could no longer find American citizens to do the work.
Now, Rosenow believes that if GOP presidential nominee Donald Trump fulfills his campaign promise to carry out mass deportations, it would devastate the $45 billion dairy industry in America’s second-largest milk producing state.
“It would basically destroy it,” said Rosenow. “There would be shortages, there would be very high prices, and that would last for quite a long time.”
Yet, in campaign stops in this crucial battleground state, Trump has promised to end what he terms a “mass migrant invasion” of Wisconsin. “They come in illegally, they take everybody’s jobs, and you don’t know who you’re hiring,” he said. “Our country is being destroyed.” Pro-Trump signs cluster the roads near Rosenow’s farm.
Rosenow, a Democrat, said local farmers who support Trump think the candidate doesn’t mean what he says about mass deportations. There was a lot of fear in the immigrant community when Trump was president and most farmers Rosenow knew lost a few employees, who fled the country. But after about six months, they started coming back.

“It’s just like a lot of things in politics,” Rosenow said. ‘Rhetoric is one thing and reality is another.”
Immigration is one of the largest issues shaping the campaign between Trump and Democratic nominee Kamala Harris. Both are promising tighter controls at the country’s southern border, but Trump has vowed to undertake an unprecedented effort to deploy the National Guard to send back millions of unlawfully present immigrants.
