MADISON, WI (WTAQ) - Governor Scott Walker’s office says Wisconsin’s new photo ID law for voting is constitutional – and it will survive a second legal challenge that came up Tuesday. The American Civil Liberties Union filed suit in federal court, two months after the League of Women Voters filed its suit in state court. Both groups say the law is unconstitutional. The Republican Walker is one of the defendants in the ACLU’s suit, which alleges that six classes of people will find it harder if not impossible to get the ID’s they need to vote. The lead plaintiff is an 84-year-old village board member from Brokaw who said she needed a copy of her birth certificate to get an ID – and to get the birth certificate, she had to pay over $200 to change a misspelled maiden name on that document. The ACLU equates that to a poll tax. Dana Brueck of the State Justice Department said the allegations are not new. Walker spokesman Cullen Werwie said at least 15 other states have adopted some form of photo ID for voting, and it’s been upheld by the U.S. Supreme Court. Werwie said the law is needed to ensure the integrity of elections. There’s been very little voter fraud across the state, which was the main argument druing the run-up to passage.
