The Hawaii Republican caucuses, 2008 were held between January 25 and February 5, 2008. The caucuses chose delegates to Hawaii's Republican State Convention in May 2008, which overwhelmingly lent its support to Presidential candidate John McCain.
Republican caucuses in Hawaii tend to be informal, taking place in parks, businesses, and homes over the course of several days. The Republican caucuses in Hawaii were closed to non-party members. None of the local delegates chosen at the caucus were committed to any candidate at the state convention. They were, however, bound to the preferences stated in the state convention in the first ballot. For this reason, Hawaiian Republican caucusgoers normally vote for convention delegates based on the delegates' personal records rather than their pledged support for a presidential candidate. However, most contenders provided slates of qualified delegates for caucusgoers to vote on.
Unlike most Republican caucuses, no straw poll or presidential preference poll was taken of the attendees. Thus, no official record was provided of Hawaiian caucusgoers' preferences for President. Hawaii's delegation to the national convention, which selected the President, was chosen only at the state convention, held in Honolulu between May 16 and 18.
The convention chose seventeen national convention delegates and seventeen alternates, all of them supporters of John McCain, already the presumptive Republican nominee for President for some weeks before the state convention. Over 450 delegates from all of Hawaii's electoral districts attended the convention. They elected state committee members and chose a party platform as well as delegates to the Republican National Convention. All in all, over 600 Republicans were at the state convention.
