Opponents of Wisconsin's voter identification law are asking the Supreme Court to keep officials from enforcing it in the November election.

Legal papers filed Thursday with the Supreme Court say there's not enough time to implement new ID requirements in the five weeks before the election.

A federal judge struck down the law last spring as unconstitutional. A three-judge ruling allowed the identification requirements to go forward. Last week, the 7th U.S. Circuit Court of Appeals in Chicago hit a deadlock on the issue, voting 5-5 and leaving the law intact.
