Arizona Revised Statutes Title 16. Elections and Electors § 16-243. National convention delegates; vote for candidates

A. The selection of delegates to the political party national conventions shall be as provided in the bylaws of each state party.

B. At the political party national convention, each delegate to the national convention shall vote for the party's presidential nominee candidate who received the greatest number of votes in the presidential preference election until the candidate is nominated for the office of President of the United States by the convention, until the candidate releases the delegate from the delegate's obligation, until a candidate withdraws from the race or until one convention nominating ballot has been taken. After a candidate is nominated, withdraws from the race, delegates are released or one ballot is taken, each delegate is free to vote as the delegate 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.
