According to research from the organization, Wisconsin has 92 DMV locations compared to Indiana’s 140 Bureau of Motor Vehicle service centers, even though Wisconsin is 50 percent larger than Indiana in square miles.

The hours at those locations are limited, with just 31 of Wisconsin's DMV centers maintaining normal business hours Monday through Friday. Only two are open after 5 p.m., and three are open on weekends.

Of the 92 DMV locations, 49 operate two days per week. One Wisconsin Institute noted in its brief that four offices are only open for six days each year and one, in Sauk City, is open for just three days this year.

Getting identification at a DMV location with such limited hours before Election Day presents a challenge. The next time the Minocqua DMV will be open is Nov. 4, the day of the election. The Wittenburg location won't be open at all between the date of the ruling and the day of the election.

Earlier One Wisconsin Institute research found that nearly all of Indiana's 140 BMV locations were open five days per week, with 124 offices open on weekends. When Indiana's law was upheld, an estimated 99 percent of eligible voters had the required ID.
