Indiana's Republican secretary of state says today's U.S. Supreme Court decision upholding the state's voter ID law means voters can have confidence in elections.
But Senate Majority Leader Harry Reid says the law places "an unnecessary burden on elderly and low-income voters" as well as minority voters.
Twenty-five states require some form of ID. Indiana's law is considered strict, requiring voters to produce a photo ID.
The court ruled 6-3 that the requirement does not violate a voter's constitutional rights.
The ruling means the ID requirement will be in effect for next week's presidential primary in Indiana. A significant number of new voters are expected to turn out for the Democratic contest between Hillary Rodham Clinton and Barack Obama.
It was the court's first significant foray into election law since the dispute over the 2000 presidential election. In Ohio, the ruling is being hailed as a victory by Republicans and others who back the Buckeye State's less stringent voter identification law. But not everyone agrees with that interpretation.
