2026 Election Picture for Hawaii
Hawaii's 2026 primary was held on August 8, 2026. Hawaii does not have a U.S. Senate seat up for election in 2026 — its senators' class isn't on this cycle's ballot. All 2 of Hawaii's U.S. House seats are on the ballot in 2026, since House terms are two years. The general election is November 3, 2026.
For context on the 2026 map: in the 2024 presidential election Harris carried Hawaii by 24.4 points.
2026 is a midterm election year — it falls in the middle of the presidential term, so there is no presidential race on Hawaii's 2026 ballot. Every U.S. House seat nationwide is on the ballot every two years, and roughly a third of U.S. Senate seats — whichever class is next in rotation — are up in every congressional election, midterm or presidential.

Senate Class Breakdown
U.S. Senators serve staggered 6-year terms split into three classes, so a state's two Senate seats usually aren't on the ballot in the same year. Hawaii's two Senate seats are staggered across different classes.
The staggered system dates to the Constitution's framers, who wanted the Senate to change gradually rather than all at once — unlike the House, where every seat turns over every two years. Roughly one-third of the Senate's 100 seats (whichever class is next up) is on the ballot in any given election year, which is why only some states have a Senate race in any particular cycle.
- Brian Schatz is Class 3 — next up for election in 2028.
- Mazie Hirono is Class 1 — next up for election in 2030.

Brian Schatz's seat (Class 3) is next on the ballot in November 2028; Mazie Hirono's seat (Class 1) is next on the ballot in November 2030. Senators serve six-year terms in three staggered classes, so a state's two seats are never on the ballot in the same regular election — neither Hawaii seat is up in 2026.
