Normally, the San Diego County Sheriff is elected by county voters every four years. But this year, it will be very, very different. Sometime this spring, instead of a potential 1.5 million registered voters going to the polls to choose one of the county's most powerful officials, the decision will be made by only five people. True, those five are themselves powerful as members of the County Board of Supervisors and collectively have spent almost 100 years in office. But since all are white and Republican in an increasingly racially diverse region where Democrats now outnumber Republicans, it is reasonable to question whether their choice would reflect the voters.
