Lana Laney, 53, of Milton said her 19-year-old son Austin Lapper turned her on to Sanders’ campaign. Laney, a single mother, said Sanders’ free college plan would have greatly helped her son’s search for the right college.

Lapper, a freshman at UW-Milwaukee, would have looked for a college better suited for his major — acting — rather than picking the college that was most affordable, Laney said.

“Tuition is outrageous,” Laney said. “It’s hard for us ... just trying to get him through college. He might have went somewhere more beneficial for his career (if tuition were free).”Urquidi said the tipping point for her in narrowing down her choices to Sanders and Trump was the desire for a candidate that had “true independence.”

“They don’t seem to be bought by special interests,” she said of Sanders and Trump.

Sanders is trailing Clinton in the delegate count, and national political observers view Wisconsin as a potential last stand for his campaign.

Clinton will campaign in Wisconsin on Monday and Tuesday, with events in Madison, Milwaukee, La Crosse and Green Bay. She is expected to talk about her plans to break down barriers that hold Americans back and to encourage state residents to take advantage of early voting, which ends Friday, according to her campaign. Additional details have not yet been announced.Clinton’s daughter Chelsea visited Madison, Milwaukee and Waukesha on Thursday.
