A.P. offers this report, which begins: “Federal officials have approved new Arizona election rules requiring voters to show identification at polling places but allowing those without IDs to cast provisional ballots. The provisional ballots would be counted only if the voters later produce identification at an election office. A requirement that voters produce identification at polling places was a provision of a voter-approved law that appeared on the state’s November ballot as Proposition 200. It took state officials until last month to work out how it would be implemented. The U.S. Justice Department approved the procedures Oct. 7 after a review for compliance with the Voting Rights Act, a federal law intended to protect minorities’ voting rights.”
