Friday 25 January - Thursday 7 February 2008: Republican Party Precinct Caucuses are held during the last 7 days of Janaury through the first 7 days of February. Each Precinct Caucus chooses the precinct's delegates to the Hawaii State Republican Convention.

• There is no formal system applied in the Precinct Caucus to relate the presidential preference of the Convention participants to the choice of the precinct's delegates to the State Convention. The participants at each Precinct Caucus alone determine if presidential preference is to be a factor in such choices and, if so, how it is to be applied.

(NOTE: there are so-called "regional caucuses" which are held in April going into early May and which nominate candidates to be delegates to the Republican National Convention who are to be considered at the later State Convention; however, these "regional caucuses" are not considered to have a direct effect on the actual allocation of National Convention delegates to the presidential contenders, as the earlier Precinct Caucuses, which have already chosen the delegates to the State Convention, have no direct and binding effect upon the makeup of these "regional caucuses".)

Friday 16 May - Sunday 18 May 2008: The Hawaii State Republican Convention convenes. Congressional District Caucuses made up of the State Convention delegates from each of Hawaii's 2 congressional districts choose the 6 district National Convention delegates (3 per congressional district). The State Convention as a whole chooses 11 (10 base at-large plus 1 bonus) of Hawaii's delegates to the Republican National Convention.

• There is no formal system of allocating Hawaii's National Convention delegates to presidential contenders. The delegates to the State Convention (whether as participants in their respective Congressional District Caucuses or in the Convention as a whole) alone determine if presidential preference is to be a factor and, if so, how it is to be applied to the choosing of the state's National Convention delegates.

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.

Rules of the Republican Party of Hawaii:

• Section 216. CANDIDATE COMMITMENTS. Except by their own commitments, National Delegates and Alternates shall not be required to support any particular candidate for the Republican nomination for President or Vice President. Candidates for delegate or alternate to the National Convention may run committed to a particular candidate for the Republican nomination for President or Vice President. Provided the candidate the delegate or alternate is supporting has not withdrawn prior to the first ballot at the National Convention, the commitment to that candidate shall be binding, but only through the first ballot.
