Who represented Hawaii in the 2025–2026 Senate?

A dated roster. Traceable sources.

This is an outgoing 2025–2026 roster baseline. It does not verify membership after the election-time term transition documented below. A candidate list or vote lead does not establish a serving member. This view does not refresh automatically.

This page is an explicitly dated 2025–2026 pre-election baseline through November 2, not a verified November 6 post-election current roster. The official incumbent directory was rechecked November 6, 2026 (America/Chicago); all 76 names and affiliations still match the older source baseline. They are retained only in that baseline context.

The November 6 recheck found the official Senate contact PDF unchanged from its August 27, 2026 revision. Central Capitol member directories and chamber homepages returned HTTP 403. A complete post-election serving directory could not be verified; the baseline is not relabeled as current membership.

Constitution Article III section 4 starts legislative terms on general-election day and ends the old House terms on that day. For the 2026 election that is November 3, rather than a January convention. Official results, projected winners, candidate filings and leads are not treated as proof of current service. No post-election successor or vacancy is inferred.

The baseline includes all 51 House and 25 Senate records as listed in the official incumbent table. Party codes are copied from that table: House 41 Democratic and 10 Republican; Senate 22 Democratic and 3 Republican. The Senate August 27, 2026 contact PDF independently agrees on all 25 district-party joins.

Baseline replacements include Matthias Kusch, Joe Gedeon, Daisy Hartsfield, Michael “Cov” Ratcliffe, Rachele Lamosao and Danielle Bass; predecessor identities are not carried forward. Elle Cochran’s March 16, 2026 switch to Republican is reflected in this baseline.

The current.status value serving means listed as serving in the retained OLD official directory for this pre-election baseline only. It is not an assertion of service after the November 3 term transition. Baseline context and period also accompany every CSV row.

Legal geometry comes from the Office of Elections final 2022 island-unit state legislative shapefiles for the January 28, 2022 final reapportionment plan, upheld in the May 9, 2022 Hawaii Supreme Court opinion. These full legal files include the Northwestern Hawaiian Islands; the separate statewide GIS display service omits that chain and is not the legal authority for this build.

Display uses Census 2024 cartographic state legislative districts. Every district ID and interior label is checked against its corresponding official final legal polygon. All source cartographic islands, rings and holes are retained, including the Northwestern Hawaiian Islands. The map opens on the main islands; All of Hawaii fits the complete state.

These are representation records and geographic display boundaries. No district demographics, ACS measures, ZIP or ZCTA findings, electoral outcomes or party attributes are inferred from geometry. This snapshot has no automatic update feed.

2025–2026 pre-election baseline affiliations come from the older official Office of Elections incumbent directory, rechecked November 6. They are not verified post-November 3 membership or election results. No successor is inferred from leads or candidate lists. This snapshot does not refresh automatically.

Legal authority: Hawaii Office of Elections final 2022 House and Senate island-unit shapefiles for the 2021 final reapportionment plan adopted January 28, 2022 and upheld May 9, 2022. Display: Census 2024 1:500,000 cartographic legislative districts; all 76 IDs and district interior labels verified against legal polygons. All cartographic rings, including the Northwestern Hawaiian Islands, are retained. Small-scale display, not address-level district determination.
