Kauai County, like Hawaii in general, has traditionally been a stronghold of the Democratic Party. The county has not voted for a Republican presidential candidate since 1984, when it narrowly voted in favor of Ronald Reagan. In 2024, while it still voted majority Democratic, Kauai County cast the highest percentage for the Republican candidate of any county in the state, a distinction that has generally been held by Honolulu County; this was the first time Kauai County had done so since 1960.[29] The island of Kauai leans Democratic overall. The island of Ni'ihau, which has a very small population, tends to vote almost entirely Republican, by far the strongest such leaning of all major Hawaiian islands.[30]
