Cal. Elec. Code § 20400
The Legislature declares that the purpose of this chapter is to encourage every candidate for public office in this state to subscribe to the Code of Fair Campaign Practices.
It is the ultimate intent of the Legislature that every candidate for public office in this state who subscribes to the Code of Fair Campaign Practices will follow the basic principles of decency, honesty, and fair play in order that, after vigorously contested, but fairly conducted campaigns, the citizens of this state may exercise their constitutional right to vote, free from dishonest and unethical practices which tend to prevent the full and free expression of the will of the voters.
The purpose in creating the Code of Fair Campaign Practices is to give voters guidelines in determining fair play and to encourage candidates to discuss issues instead of untruths or distortions.
