Wisconsin's voter identification law may have cost Sec. Hillary Clinton as many as 45,000 votes. Donald Trump won the state of Wisconsin by 22,748 votes.
A comprehensive study released today suggests how many missing votes can be attributed to the new law. Researchers at the University of Wisconsin-Madison surveyed registered voters who didn’t cast a 2016 ballot in the state’s two biggest counties—Milwaukee and Dane, which is home to Madison. More than 1 out of 10 nonvoters (11.2 percent) said they lacked acceptable voter ID and cited the law as a reason why they didn’t vote; 6.4 percent of respondents said the voter ID law was the “main reason” they didn’t vote.
The study’s lead author, University of Wisconsin political scientist Kenneth Mayer, says between roughly 9,000 and 23,000 registered voters in the reliably Democratic counties were deterred from voting by the ID law. Extrapolating statewide, he says the data suggests as many as 45,000 voters sat out the election. “We have hard evidence there were tens of thousands of people who were unable to vote because of the voter ID law,” Mayer told me.
