MADISON, Wis. (AP) – The Wisconsin Supreme Court is set to rule on a 2011 law requiring that voters show photo identification at the polls. The law has already been ruled unconstitutional in April by a federal court judge in Milwaukee. That decision is being appealed. For the law to take effect, both the state Supreme Court and the federal courts would have to find it to be constitutional. The Supreme Court was to release its decision Thursday morning. The voter ID requirement was only in force for one low-turnout spring 2012 primary before being blocked by a state judge. The cases before the Supreme Court were brought separately by the League of Women Voters and the Milwaukee branch of the National Association for the Advancement of Colored People.
