Precinct Caucuses (preliminary)
Included in Nationwide vote.

All 19 of Hawaii's delegates to the Republican National Convention are pledged proportionally to presidential contenders in today's Precinct Caucuses. [Rules of the Hawaii Republican Party. Section 214.]

• Each Presidential campaign (or uncommitted slate) supplies a list of delegates to the National Convention. 20% of each slate (delegates and alternates) must come from a county with a population below 500,000. The State Chair and National Committee members cannot be part of a slate. [Rule 215. E.]
• Voting is by secret ballot. Ballots are cast for the slate rather than for individual delegates. The names of the National Convention delegates will not appear on the ballot.
• Voters may join the Republican party and register to vote at the caucus. Only party members are eligible to participate in the caucuses.
• Blank votes, spoiled ballots, over votes, and write-in votes for a candidate who is not registered with the FEC as a Republican candidate for President are not considered to be valid.
• Allocate the National Convention Delegates:
1. Starting with the highest vote getter, compute the Delegate Allocation Percentage-- the candidate's votes divided by the total number of votes (in that jurisdiction) and round the percentage up to the next whole number. Then, multiply the number of delegates (in that jurisdiction) by the Delegate Allocation Percentage and round up to the next whole number. Continue with the next highest vote getter until all delegates are pledged to a presidential contender. The number of delegates allocated to each jurisdiction is:
• CD 1: 3 delegates.
• CD 2: 3 delegates.
• Statewide: 10 delegates (10 base at-large delegates plus 0 bonus delegates).
• RNC: 3 delegates.
• The Hawaii Leadership Committee of each Presidential campaign appoints Party members to fill the delegate positions. [Rule 215. E.]

In addition, 3 party leaders, the National Committeeman, the National Committeewoman, and the chairman of the Hawaii's Republican Party, will attend the convention as pledged delegates by virtue of their position. [Section 216.]
