Hawaii Democratic Primary Highlights Intraparty Divide

A High-Stakes Contest in Hawaii

Hawaii voters are casting their ballots in a pivotal Democratic primary for the state’s 1st Congressional District. This election features a contest between experience and generational change, representing a broader division within the party. The incumbent, Representative Ed Case, age 73, a moderate with two decades of Washington experience, is challenged by State Senator Jarrett Keohokalole, age 43.

Voter Sentiment and Polling Data

Polling data indicates a competitive race as Election Day approaches. Prediction Edge averages from surveys between October 2025 and July 2026 show Case with 39.8% support, Keohokalole with 27.3%, and former candidate Della Au Belatti at 21%. Belatti withdrew to campaign for lieutenant governor.

The New York Times polling tracker confirms Case in the lead but not secure. A Blueprint Polling survey on July 24 depicted Keohokalole ahead, 47% to Case’s 38%. However, earlier in July, Case led by 8 points—33% to 25% in another Blueprint poll, both sponsored by Keohokalole. Prediction markets highlight a narrower margin, indicating a 56% victory chance for Case compared to 48% for Keohokalole.

Establishment vs. Progressive Visions

The campaign underscores different leadership approaches for this reliably Democratic, Honolulu-based district. Previously, Case secured reelection with around 72% of the vote, while Democratic Vice President Kamala Harris secured 62% against Trump. Case emphasizes his seniority and his role on the House Appropriations Committee, which he sees as vital for Hawaii’s interests, such as pandemic recovery and addressing the Red Hill water crisis and Maui wildfires.

“You can argue it all you want, but in Congress seniority matters,” Case expressed to Hawaii Public Radio.

Keohokalole advocates for a generational shift, promoting aggressive stances on affordability, healthcare, and national policy. He critiques Case’s record, including support for Trump’s SAVE Act. Case clarified to Hawaii Public Radio that the version he endorsed allowed necessary voter accommodations.

Implications and Forward Look

This primary reflects a trend where progressive challengers target seasoned House Democrats, sparking debates over leadership and party direction. Despite Case’s advantages in recognition and resources, a win for Keohokalole might indicate a Democratic base eager for younger leadership.

The victor will face unopposed Republican Adriel Lam in the November general election. Hawaii primarily conducts elections by mail, with under 2% of 2024’s state primary voters voting in-person. By the recent count, about 179,000 ballots have been submitted for Saturday’s election. Polls close at 7 p.m. local time, correlating to 1 a.m. ET Sunday.
