    Hawaii holds primary elections for congressional and gubernatorial seats

    Official election results show Case winning with 57% of the vote

U.S. Representative Ed Case (D-HI) won the Democratic primary for his Honolulu-based congressional seat on Saturday, according to official election results. Case, who has held the seat since 2019, received 57% of the vote to defeat challenger Jarrett Keohokalole, who received 34%. The primary also included three other candidates seeking the nomination for the district.

The primary race highlighted internal divisions within the Democratic party, where established lawmakers have faced challenges from progressive newcomers. Case, described as a moderate, previously served in the House from 2002 to 2007 before his current tenure. His victory in Hawaii occurred alongside other Democratic primary contests, including U.S. Representative Jill Tokuda’s win with 84% of the vote and Governor Josh Green’s successful defense against several challengers.

During the campaign, Case emphasized his seniority on a key spending committee, arguing that his reelection is necessary for Hawaii to continue attracting federal funding. Keohokalole, 43, criticized Case’s reliance on campaign donations from businesses, stating that the incumbent had lost touch with the electorate. The district is considered safely Democratic for the upcoming November general election.

The scale of the victory—a 23-point margin over the closest challenger—indicates a preference for Case’s moderate platform over the progressive platform offered by Keohokalole. While progressive candidates have recently seen a surge in states like Colorado, Kentucky, and New York, this result shows that established incumbents in Hawaii retain significant support. Voters in this district will not see a change in their representative's approach to business donations or committee leadership, issues that were central to the primary debate.

This win reinforces the position of veteran lawmakers within the Democratic party structure and sets the stage for the November general election. Because the district is heavily Democratic, the primary winner is the heavy favorite to win the general election seat. The next major step for voters in this district will be the general election in November, where Case will face his Republican and third-party opponents to finalize who will represent Honolulu in the next Congress.
