About the Campaign Guide

This Campaign Guide has been prepared to assist candidates, committees, and members of the news media in preparing for the upcoming 2020 Consolidated General Election.  It is not intended to be all-encompassing, but merely a summary of major provisions related to candidates and committees involved in elections in the County of Sonoma and the State of California.

While staff has attempted to be as informative as possible in compiling this information, and we appreciate the opportunity to address your questions not answered in this handbook, the law prohibits employees from answering questions of a legal nature.  This handbook is not intended as a substitute for legal counsel.  For your protection, we strongly urge you to consult an attorney.
