With 22.6 million registered voters in the state, this is 17% of registered voters. The number of foreign born voters registered in recent years far exceeds the number of naturalized citizens. The cause of this difference is that in California, individuals who apply for drivers licenses are automatically added to the voter rolls (Motor Voter). This and the barriers to verifying citizenship have led to millions on the voter rolls who aren’t US citizens. Ballot harvesting is still in place and all registered voters receive a ballot for the election in the mail.
