Hawaii Rep. Ed Case demolished his progressive challenger by nearly 24 points Saturday, proving that even in deep-blue Honolulu, voters won't swallow the left's full agenda when they get a real choice.

Case, one of just three House Democrats who voted for Trump's SAVE Act requiring proof of citizenship to vote in federal elections, turned what Fox News called his "toughest primary challenge yet" into a blowout. The result exposes the ceiling on the progressive primary spree that has already ousted moderate incumbents in New York and Colorado this year — and it starts where open-borders politics and anti-enforcement posturing begin.

With 91% of votes counted, Case had won 60% to state Sen. Jarrett Keohokalole's 36.1%, according to the Associated Press. Keohokalole, 43, campaigned on a "new generation" of leadership and backed Medicare for All, abortion rights, and what his campaign website called the "unconstitutional encroachment of ICE in our communities," according to Breitbart. CBS News reported Keohokalole also hit Case for voting to send military aid to Israel.

Case, 73, leaned hard into his independence. "I'm not 100% voter with my party," he told HawaiiNewsNow. "Never have been, never will be."

The flashpoint was the SAVE Act. Keohokalole accused Case of "appeasing Trump, when he's taking away the right to vote, one of the foundational freedoms in this country," according to Hawaii News Now. Case later withdrew support from the updated bill after it stripped a provision allowing voters without citizenship documentation to attest in writing that they are citizens. In Hawaii, falsely attesting to citizenship on a voter registration form is already a felony, the Washington Examiner noted.

The Guardian and CBS News both labeled Case a "moderate" — the standard press tag for any Democrat who breaks with the party on immigration enforcement. But requiring proof of citizenship to vote in federal elections isn't some centrist compromise; it's what most Americans expect. The "moderate" framing is the tell: the establishment media considers common-sense election integrity a rightward deviation.

Case argued his seniority delivers tangible results — aid during COVID, the Red Hill fuel leak crisis, and the Maui wildfires. "You can argue it all you want, but in Congress seniority matters," he told Hawaii Public Radio. He also holds a senior slot on a key spending committee and warned Hawaii would pull fewer federal dollars without him.

Keohokalole countered that Case's business donations showed he'd lost touch — a standard progressive line that didn't resonate with voters who apparently care more about results than fundraising purity.

The endorsement split was telling: Case landed Planned Parenthood Action Fund and the American Federation of Government Employees, while Keohokalole rallied state labor unions and Our Revolution, the group Bernie Sanders founded in 2016, per the Washington Examiner.

Case faces Republican Adriel Lam in November. Given Hawaii's Democratic lean, he's favored to keep the seat.

Progressive insurgents have notched real wins this cycle. But Case's landslide raises the question the left doesn't want to answer: how far can you push a party whose own voters still want borders enforced and elections secured?
