HONOLULU — U.S. Sen. Mazie Hirono and the state’s incumbent congressional representatives were victorious in the Democratic Party’s primary election on Saturday.

Hawaii, a vote-by-mail state, sent ballots to registered voters, who could return them through the mail or at drop-off boxes across the islands. Voters also had the option to cast ballots in person at designated voter service centers in each county.

Ballots were required to reach county elections offices by 7 p.m. on Election Day to be counted.

Here is a breakdown of key Hawaii races:

U.S. Senate

Hirono is vying for a third term after her initial election to the office in 2012, replacing Daniel Akaka, the first Native Hawaiian to serve in the U.S. Senate post-statehood.

She emerged victorious in a three-way contest against Ron Curtis and Clyde McClain Lewman. Curtis previously lost to Hirono in the general election six years ago as the Republican nominee for the same seat. Lewman secured seventh place in the 2022 Democratic gubernatorial primary with a mere 249 votes.

Hirono’s political journey began in 1980 as a state legislator, transitioned to Hawaii’s lieutenant governor in 1994, and culminated in a U.S. House seat in 2007.

In 2017, she underwent surgery for kidney cancer, a year prior to her re-election to a second six-year term in the Senate.

Former state Rep. Bob McDermott outmaneuvered five lesser-known contenders for the Republican Senate nomination. McDermott’s last Senate bid took place two years ago, resulting in a defeat against U.S. Sen. Brian Schatz, a Democrat, in the general election by a substantial 44-point margin.

U.S. House

U.S. Rep. Ed Case secured the Democratic Party primary win for representing Hawaii’s 1st Congressional District in Congress by defeating Cecil Hale.

Case initially won the seat representing urban Honolulu in 2018, having previously held the position for Hawaii’s 2nd Congressional District from 2002 to 2007.

Patrick Largey ran unopposed in the Republican primary.

In the 2nd Congressional District race, U.S. Rep. Jill Tokuda faced no opposition in the Democratic primary, and Steve Bond ran unopposed in the Republican primary. The district encompasses suburban Honolulu and the neighbor islands.

State House

House Speaker Scott Saiki faces a challenging race against Kim Coco Iwamoto, who is making another bid after narrowly losing to Saiki by a mere 161 votes two years ago and 167 votes in 2020.

Their state house district covers downtown Honolulu and Kakaako, an area undergoing a construction boom that has transformed warehouses into high-rise condominiums.

Saiki, an attorney, has served as House speaker since 2017 and as a state representative for three decades. His campaign website highlights legislation passed this year that he claims would provide a 70% tax cut to working-class families.

Iwamoto, also an attorney, represented Oahu on the state Board of Education from 2006 to 2011. Her website asserts that she is committed to exposing government corruption and waste, and advocating for adequate shelter and social workers to address homelessness.

Iwamoto was recognized as the highest-ranking openly transgender person elected in the country when she first won her education board seat 18 years ago.
