American conservatism was carried over to the Party from the ABCFM missionaries, a few issues continue to the present party such as support for democracy, stop and preventing drug and alcohol abuse, and opposition to gambling in the islands. As compared with the national Republican Party, Republicans in Hawaiʻi who hold elective office tend to be moderates. On social issues such as abortion, they tend to be somewhat less conservative than the national party as a whole. For example, former Republican Governor Linda Lingle is pro-choice, but favors parental notification. In large part from HB 444 the party has taken a populist stance in that social issues should be based on public opinion, while opponents have argued that populist policies would lead to exclusion and discrimination toward minority groups.
As a whole, Hawaiʻi Republicans advocate limited government, lower taxes, decentralized control of public schools, and improving Hawaiʻi's business climate. Republicans have been supportive of big business plans and commitments to allow companies in Hawaiʻi to rival and compete against large businesses in other states. Republicans have also been supportive of interstate and international commerce. For example, former Lieutenant Governor James "Duke" Aiona has been a strong proponent of keeping the National Football League’s Pro Bowl in Hawaii. Former Governor Linda Lingle proposed tax reduction incentives to businesses to hire and encourage work, such as hotel renovations.
Reform Party (a group largely sympathetic toward the Republican Party following annexation) member Lorrin Thurston was a strong supporter of the formation of Hawaii Volcanoes National Park. Governor Lingle proposed a Clean Energy Initiative to encourage and promote clean and renewable energy reasorces. The goal of the Initiative is to make Hawaii 70% energy self-sustainable by 2030. The indicative uses solar, wind, ocean, geothermal, and biomass as energy resources and a phased reduction in the use of fossil fuels.
Recently, the Party has been hesitant to associate itself with religion in general, with members citing the negative effects of the party's association with the Hawaii Christian Coalition formed by Pat Robertson in 1988. The Coalition swelled Republican membership by 50% but at the expense of infighting and by 1993 the party had lost more legislative seats than it started with.
