Tens of thousands of Californians have been registered to vote incorrectly by the state Department of Motor Vehicles, including some who were assigned the wrong political party preference, officials said Wednesday.

Officials insist the errors were limited to 23,000 of the 1.4 million voter registration files sent to elections offices between late April, when California’s new automated “motor voter” system went into effect, and early August. Californians who were affected will soon receive notifications in the mail instructing them to check their voter registration status.

Jean Shiomoto, the state’s DMV director, and Amy Tong, director of the California Department of Technology, described the problem as “an administrative processing error” in a letter to Secretary of State Alex Padilla, California’s chief elections officer.
