California’s elections officials have found themselves with an unexpected headache ahead of the June 5 primary: potentially thousands of cases where two voter registration forms were created for one person, errors caused by the state’s “motor voter” program that launched last month.

But local and state officials said Wednesday they don’t believe the foul-up has resulted in actual mistakes in California’s voter database. The errors are being resolved one at a time in each county’s elections office, a lengthy process that coincides with one of the busiest periods of the year.
