- Hawaii voted Saturday, and the favorites swept the board. The one race with real suspense was in the 1st District, where Rep. Ed Case held off a primary challenge from the left.
- The markets got the winner but missed the margin the other way. Polymarket had made it a near coin flip, with Case around 50 percent, yet he won comfortably, holding his challenger to about 35 percent.
- The anti-incumbent wave that toppled members in New York and Michigan did not reach Hawaii. Case's seniority and record carried him past 42-year-old state Sen. Jarrett Keohokalole.
- Gov. Josh Green cruised to renomination with 81 percent and is a lock for a second term in a state that has not elected a Republican governor since 2006.
- Kauai Mayor Derek Kawakami won the open race for lieutenant governor, filling a seat left vacant by a scandal, and joins Green's ticket.
HONOLULU - Hawaii voted Saturday, and the night had exactly one race worth betting. It went to the favorite, just not the way the odds suggested. Rep. Ed Case, the 73-year-old moderate who has held the 1st District seat for 13 years, turned back a challenge from the left, and he did it easily. The prediction markets had spent weeks treating the race as a coin flip, and some saw the makings of another incumbent upset. Instead, Case won going away. In a state this blue, that primary is the whole contest, and the rest of the ballot went to form. The full board is on the Hawaii election odds.
HI-01: Case Survives, and Comfortably
The race the whole country was watching was Case against state Sen. Jarrett Keohokalole, and it was not close. Keohokalole took about 35 percent, which means Case won with roughly two-thirds. That is a striking result, because it is not what the market expected. On the House race odds, Polymarket had Case near 50 percent and Keohokalole around 43, a true coin flip, and the anti-incumbent mood of 2026 had traders and pundits eyeing an upset. Members had already fallen to primary challengers in New York and Michigan this cycle. It did not happen here. Keohokalole, 42, ran on generational change and hammered Case's moderate voting record, but Case leaned on his seniority and his record of delivering for Hawaii, and the voters stuck with him. For bettors, it is the mirror image of the usual lesson. The market did not oversell a favorite here. It undersold one, pricing a comfortable winner as a toss-up. Case will win the safely blue seat in November.
Governor and Lieutenant Governor
At the top of the ballot, there was no drama. Gov. Josh Green, a former ER doctor, won his Democratic primary with 81 percent over three minor challengers and is a heavy favorite for a second term. On the governor race odds, the general is rated Safe Democratic, and Hawaii has not elected a Republican governor since 2006. The more interesting race down the ballot was for lieutenant governor, which Hawaii fills in a separate primary. The seat came open under a cloud. Sitting Lt. Gov. Sylvia Luke withdrew this year amid a campaign-finance scandal and was later indicted, and Green called for her resignation. Into that opening stepped Kauai Mayor Derek Kawakami, who won the Democratic nomination and now joins Green's ticket. In the 2nd District, Rep. Jill Tokuda won her primary with 83 percent and is safe for the fall.
The Bettor's Read
Hawaii was a clean night for favorites and a useful one for bettors. Every front-runner won: Green, Case, Tokuda, and Kawakami. The one lesson worth keeping came from HI-01, where the market priced a coin flip and got a blowout. The anti-incumbent wave that defined some primaries this year did not travel to the islands, and a well-known incumbent's edge turned out to be underpriced. It is a reminder that not every veteran is in danger just because a few were. From here, Hawaii has almost nothing left to bet. The general election is Safe Democratic up and down the ballot, so the winners on Saturday are, in effect, the winners in November. As always, refresh before you act. For the full board of election odds, Hawaii closed the summer primary season with the favorite winning, just by more than the odds ever gave him.
