The Washington Post has a nice story covering the decision by the Supreme Court that allows the law to be in effect for the upcoming election.

The Supreme Court ruled yesterday that Arizona may enforce a new state law requiring voters to show a photo identification card at the polls on Election Day this year, despite a pending lawsuit by opponents who say the measure will disenfranchise the poor, minorities and the elderly.

In its unanimous five-page ruling, the court did not decide whether the Arizona law was constitutional. Rather, it overturned a federal appeals court in San Francisco that would have blocked enforcement of the law until the opponents’ suit could be decided.
