The 1966 Hawaii gubernatorial election was Hawaii's third gubernatorial election. The election was held on November 8, 1966, and resulted in a victory for the Democratic candidate, incumbent Governor of Hawaii John A. Burns over Republican candidate, State Senator Randolph Crossley. Despite the close race, Burns received more votes than Crossley in every county in the state except Honolulu, which Crossley won by less than one percentage point.
This, along with the 1998 election, are the only gubernatorial elections in the state's history where a Democrat won without sweeping every county.
Primaries.
Neither the Democratic nor Republican primaries, both of which were held on October 1, 1966, were particularly contentious. In the Democratic primary, John A. Burns received 79.49% of the vote to G.J. Fontes' 20.51%. Randolph Crossley received 98.08% of the Republican primary vote to 1.92% for Gottfried Seitz.
