Notwithstanding any other provision of law, a space shall be provided on the presidential primary ballot for an elector to write in the name of a candidate for President of the United States.
Any person who believes his or her name may be used as a write-in candidate for President of the United States shall, not later than 21 days before the primary election, file his or her endorsement of his or her write-in candidacy with the Secretary of State, or no votes shall be counted for him or her.
Any person who receives, by write-in vote, a plurality of the votes cast for President of the United States shall, within 10 days after the primary election, file a list of delegates to the national convention of his or her political party with the Secretary of State in the manner prescribed in Section 6471.
If the candidate fails to file a list of delegates, the state central committee of the party in whose primary the candidate received the plurality vote shall, within 10 days of the end of the 10-day period required in Section 6442, file a list of delegates with the Secretary of State. The delegation shall go to the convention unpledged to any candidate.
