The League of Women Voters of Wisconsin has filed a brief in the voter purge case before the Wisconsin Supreme Court. The case, brought by the conservative Wisconsin Institute for Law and Liberty argues state law requires the Wisconsin Elections Commission to remove individuals if they don’t respond to a postcard verifying their address within 30 days. Commission policy allows voters to stay on the voter rolls for up to two years after the mailing is sent. League executive director Debra Cronmiller says the brief was filed to protect voters from being erroneously removed from polling lists of registered voters. The mailing goes to people flagged as potentially having moved. But Cronmiller says thousands of people who received the postcard have said they didn’t move and simply tossed the postcard in the garbage. WILL argues the agency’s policy could make Wisconsin vulnerable to voter fraud. Cronmiller says there’s no evidence of that.
