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 in the United States that has always been held by an ethnic minority. 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.
