HARRISBURG - Pennsylvania elections officials say they haven't encountered any problems with the state's new voter identification law.

Secretary of State Carol Aichele says she visited some polling places in Philadelphia on Tuesday and concluded the new law seemed to be working well.

Poll workers are asking for photo IDs in the primary, but they won't be mandatory until November.

The Department of State says its Bureau of Commissions, Elections and Legislation hasn't fielded any concerns from county elections officials about the voter ID law.

Pennsylvania Republicans are picking a nominee for president, although former Massachusetts Gov. Mitt Romney hasn't had serious opposition since former Pennsylvania Sen. Rick Santorum dropped out two weeks ago.

Other primary races include U.S. senator, and state attorney general on the Democratic side.
