Hawaii was admitted to the Union on August 21, 1959, and elects U.S. senators to classes 1 and 3 . Seven people including only one Republican have served as a U.S. senator from Hawaii. The state's current U.S. senators are Democrats Brian Schatz and Mazie Hirono . Hawaii's class 1 seat is the only one in the United States that has always been held by an ethnic minority.[ citation needed ] [ citation needed ] Hawaii is one of seventeen states alongside California , Colorado , Delaware , Georgia , Idaho , Louisiana , Maine , Massachusetts , Minnesota , Missouri , Nevada , Oklahoma , Pennsylvania , South Dakota , Utah and West Virginia to have a younger senior senator and an older junior senator.[ citation needed ]
Hawaii last elected a Republican in 1970, which has resulted in the longest streak in the nation for a state's having all-Democratic senators. Daniel K. Inouye was Hawaii's longest-serving senator, from 1963 to 2012. Hawaii is the only U.S. state that has never defeated an incumbent senator in either a primary or general election.[ citation needed ]
