CA SB113

Lowers the minimum age for voter registration affidavits from 17 to 16 years old, with registration becoming effective on the person's 18th birthday if information remains current.

Requires county elections officials to send a "voter preregistration notice" (instead of standard voter notification) to 16- and 17-year-olds who submit registration affidavits, informing them they may vote in elections held on or after their 18th birthday.

Exempts county elections officials from mailing residency confirmation postcards to persons under 18 who submitted preregistration affidavits and will not be 18 years old by the primary election.

Updates voter registration program materials to inform the public that persons at least 16 years old may preregister to vote, while maintaining that voters must be at least 18 years old at the time of election.

Makes most provisions operative only upon Secretary of State certification that California has a statewide voter registration database complying with the federal Help America Vote Act of 2002.
