ERIC collects data from voter registrations and matches them with information from the Wisconsin Department of Motor Vehicles and the U.S. Post Office. Milwaukee Election Commission Executive Director Neil Albrecht said thousands were deactivated when they didn't perfectly align.
"The DMV did what was described by the state as providing overzealous data meaning they also included if a person had a vehicle registered at another address which people who own multiple homes in the state often do," Albrecht said.
Milwaukee Mayor Tom Barrett doesn't think there is any foul play involved, but worries impoverished communities may suffer as a consequence.
"To me, the impact of that really matters more than the intention," Pettee said.
The Milwaukee Election Commission is asking the state to reverse these voter deactivations until the end of the year. Early voting is already underway for the spring election. You can register and vote at City Hall or wait until April 3 and do so at your polling place.
