Rep. Ed Case held off his most serious primary threat in years on Saturday, defeating state Sen. Jarrett Keohokalole in the Democratic primary for Hawaii’s 1st Congressional District. The Associated Press projected the race for Case with 91% of the vote counted. The 73-year-old incumbent was nearly 14 points ahead of his 42-year-old challenger.
By the second batch of returns that night, the Honolulu Star-Advertiser reported Case leading Keohokalole 60% to 36%. The gap widened as additional precincts reported. The margin marked a clear result in a race that national outlets had flagged months earlier as a potential upset in the making.
Case’s SAVE Act vote became the central line of attack
Keohokalole built his campaign around generational change. He portrayed the 73-year-old incumbent as out of step with a Democratic base seeking a sharper response to President Donald Trump. He also targeted two specific votes: Case’s support for military aid to Israel and his backing of an earlier version of Republicans’ Safeguard American Voter Eligibility Act.
Case was one of only three House Democrats to join Republicans in the April 2025 vote. Critics argued that his decision weakened protections surrounding voter rolls. Case later broke from that position. He joined nearly all other House Democrats in opposing the follow-up SAVE America Act. Case also told Hawaii News Now that he did not support the newer version of the bill.
The contrast between the two votes became a proxy for a larger question Democratic primary voters have wrestled with all year: whether incumbents who occasionally side with Republicans still deserve renomination in an era defined by Trump’s second term.
Hawaii bucked a trend that toppled six Democratic incumbents
Case’s win stands apart from a pattern that has reshaped House Democrats’ ranks since early summer. Two Mamdani-aligned challengers unseated Reps. Dan Goldman and Adriano Espaillat in New York in late June. Brad Lander defeated Goldman by 24 points, while Darializa Avila Chevalier beat Espaillat by fewer than four points.
Colorado followed days later. Democratic socialist Melat Kiros, a 29-year-old lawyer and doctoral student, defeated 15-term Rep. Diana DeGette in a Denver district DeGette had represented for almost three decades. Taking the stage afterward, Kiros told supporters, ‘This is a movement’, framing her win as part of a broader uprising against party leadership.
By the count tracked in a Fox News analysis of the 2026 cycle, Kiros’ victory was the 27th progressive primary win of the year. The tally includes contests stretching from New York and Colorado into Missouri, Michigan and Wisconsin.
Six of the nine House incumbent losses this cycle have involved Democrats challenged from the left. The remaining three were tied to Texas redistricting rather than ideology.
Case’s result breaks that streak in a district where Democratic primary turnout typically favors the party’s more engaged, further-left voters. Unlike DeGette or Goldman, Case entered the race with a financial advantage. Both campaigns raised significant money, but Case held more cash at the outset.
Case has represented parts of Oahu on and off since 2002
Case’s path to Congress began in a 2002 special election, when he won a 44-candidate field to fill the seat of the late Rep. Patsy Mink, who died of pneumonia that year. He left the House in January 2007 after an unsuccessful Senate bid, then returned in 2019 after winning a seven-way primary for Hawaii’s 1st District, which covers Honolulu and much of urban Oahu.
That history has made Case a familiar figure willing to break with his party when he judges the moment requires it. In July 2024, he was among the House Democrats who publicly called on then-President Biden to withdraw from the race. Defending the decision at the time, Case said, ‘This has nothing to do with his character and record.’ He distanced his position from any personal criticism of Biden.
The primary result sets up a lopsided general election
Case now advances to face Republican Adriel Lam, who ran unopposed in the GOP primary, in the Nov. 3 general election for a seat in a heavily Democratic district. Hawaii Gov. Josh Green secured his party’s nomination Saturday after defeating three lesser-known primary challengers. Rep. Jill Tokuda also cruised through her primary in the neighboring district with more than 90% of the vote.
The Hawaii results give Democratic Party leaders a data point to counter the narrative built by this summer’s incumbent defeats. Whether that holds through the remainder of the primary calendar depends on races still ahead in states where progressive challengers are actively organizing against sitting members of Congress.
Redistricting complicates any single national story
Not every incumbent loss this cycle traces back to ideology. Reps. Al Green and Julie Johnson of Texas lost their primaries after redistricting altered their districts’ boundaries. Their defeats reflected a different dynamic from the ideological challenges that shaped the New York and Colorado races.
That distinction matters for reading Case’s win correctly. His district lines did not change this cycle, meaning Saturday’s result reflects voter preference rather than a redrawn map favoring the incumbent.
Keohokalole, a state senator since 2014, entered the race as the most credible of several Democrats seeking to unseat Case this cycle. He fell short in a district where Case has now won primary contests across three decades. Those victories span a Mink-era special election, a seven-way field in 2018, and Saturday’s generational contest against a challenger four decades his junior.
The result leaves party strategists with a mixed picture heading into the fall. Six Democratic incumbents have lost renomination this year. Case’s margin suggests that a well-funded, long-tenured lawmaker who reverses an unpopular vote can still withstand the generational argument that unseated colleagues in New York and Colorado.
