The Democratic primary for Hawaii’s 1st Congressional District remains tight ahead of the August 8 vote, with trader consensus reflecting a narrow edge for incumbent Ed Case over state Sen. Jarrett Keohokalole. Case benefits from name recognition and traditional Democratic establishment ties, while Keohokalole has drawn endorsements from progressive groups and donors critical of Case’s record on maritime policy and other priorities. Recent developments include heightened campaign spending by both sides, national attention after the New York Times listed Case among vulnerable incumbents, and a series of late-cycle endorsements that have kept the contest competitive. Minor candidates have not emerged as significant factors, leaving the outcome dependent on turnout among Oahu Democratic voters in the final week.
