PHOENIX (AP) - The Arizona Democratic Party is suing Secretary of State Michele Reagan for refusing to extend the state's voter registration deadline by a day even though it fell on a state and federal holiday.

The suit filed in federal court Wednesday seeks an order requiring Reagan to place anyone who filed an otherwise valid registration by Oct. 11 on the voter rolls for November's election.

Reagan refused to move the Oct. 10 deadline even though there was no mail service and state Motor Vehicle Division offices were closed because of Columbus Day. The suit says more than 40 percent of voters register in-person or by mail, and no one could register in person after Oct. 7 or by mail after Oct. 8.

The Associated Press reached out, but Reagan's spokesman wasn't immediately available to comment Thursday.
