Elec. Code, § 6461

(a) The delegation of each candidate shall be composed as follows:

(1) Seventy-eight percent of the delegation, or the nearest whole number thereto which provides for a total number of district delegates equal to at least three times the number of congressional districts within the state, shall be composed of three delegates selected for each congressional district.

(2) The remainder of the delegation shall be composed of delegates selected at large from throughout the state.

The names of the persons chosen as delegates shall be submitted to the Secretary of State, by the candidate or his or her designee, no later than 30 days before the presidential primary election for certification.

(b) There shall be no more than one alternate per delegate. Alternates shall be appointed by the candidate or his or her designee and shall be appointed by congressional districts, the number per congressional district to be no less than three. Such alternates shall be submitted to the Secretary of State within 30 days after the primary for certification.

(c) Each delegate to the Republican National Convention shall use his or her best efforts at the convention for the party’s presidential nominee candidate from California to whom the delegate has pledged support until the person is nominated for the office of President of the United States by the convention, receives less than 10 percent of the votes for nomination by the convention, releases the delegate from his or her obligation, or until two convention nominating ballots have been taken. Thereafter, each delegate shall be free to vote as he or she chooses, and no rule may be adopted by a delegation requiring the delegation to vote as a body or causing the vote of any delegate to go uncounted or unreported.
