UPDATE- I used the Wisconsin State General Accounting Board website’s data for inferring an opinion (in my original post) which did not include requirements found at the official Wisconsin Voter Information page. Further research revealed an ID is required and is apparently a rather recent change in voter laws for Wisconsin, and I might add- for the better.
