SLO County supervisors to decide on voting system to be used in future elections SAN LUIS OBISPO, Calif. -- The San Luis Obispo County Board of Supervisors are set to discuss and decide which voting model the County will use for future elections. In addition, County Clerk-Recorder Tommy Gong will provide a presentation describing the two potential election models to be considered, as well as results from a Voter Survey recently conducted by his office. At the heart of the debate is to proceed with one of two elections models, in-person polling places or a Voters Choice Act (VCA) system that requires ballots mailed to every registered voter.
