Kamala Harris is campaigning in La Crosse, Wisconsin as the election approaches

“I honestly think he understood how tariffs work before,” Cuban said. “In the ’90s and early 2000s he was a little coherent when he talked about trade policy and he actually made a little sense. But I don’t know what happened to him.”

In a speech Thursday in Pittsburgh, Trump’s vice presidential nominee, Republican Sen. JD Vance of Ohio, pushed back against the Harris campaign’s claims that tariffs would hurt the economy. Vance described the tariffs as a way to curb imports and boost American manufacturing.

“If you are a business and you rely on foreign slave labor for $3 a day, the only way to rebuild American manufacturing is to say: If you bring the product made by slave labor back to the United States of America “We’re going to pay a big tariff before you bring it back into our country,” Vance said.

In Wisconsin, Amara Marshell, a freshman at UW-La Crosse, said she came to support Harris because she was concerned about what a second Trump presidency could mean for reproductive rights. Like her friend, sophomore Avery Black, Marshall is excited about the opportunity to elect the country’s first female president.

“Women deserve to have power over their own bodies,” Marshall said. “We shouldn’t have to not have an abortion just because of a president.”

Mary Holman, an 80-year-old retiree from Fort Atkinson, Wisconsin, said she had not been to a rally since former President Barack Obama’s first campaign in 2008 and viewed the election as a fight to preserve democracy.
