Hawaii Republicans will have their first binding presidential caucus this year, and remaining candidates Mitt Romney, Newt Gingrich, Rick Santorum and Ron Paul are all angling to pick up delegates.
In the past, party leaders in Hawaii would select the state's delegates to the national convention. Hawaii, Barack Obama's home state, has gone Democratic in nearly every presidential election since statehood.
This year, Hawaii Republicans have done away with straw polls and a more convoluted system to hold a transparent, binding and closed caucus, meaning only registered Republicans can vote. State party Chairman David Chang hopes that the move will energize GOP supporters and build up party membership.
It's certainly caught the Republican candidates' attention more than any GOP event in Hawaii in years.
Although none of the candidates have made a campaign stop in the islands, three of them -- former Massachusetts Gov. Mitt Romney, former Pennsylvania Sen. Rick Santorum and Texas Rep. Ron Paul -- have sent members of their family to the distant island state.
Santorum's daughter Elizabeth, Romney's son Matt and Paul's son Ronnie all held campaign events over the weekend and on Monday and Tuesday, reaching out to undecided voters on school campuses and holding conference calls with Hawaiians to ask for their support. The Paul campaign also paid for TV airtime, while Santorum paid for a robo-call to voters.
Newt Gingrich, meanwhile, looking to score big in Mississippi and Alabama on Tuesday night, nonetheless made several trips with his wife to the islands earlier this year, and reportedly sent out a letter last week asking the state's Republicans for their support.
It's very exciting, Chang told Fox News on Monday. The three campaigns are generating a lot of buzz from voters who might not otherwise have known much about the candidates.
