House District 81 has a sourced reelection call for Daniel Gosa and is not a district change. Senate District 14 is expected to become vacant when Sarah Trone Garriott moves to Congress; its unknown replacement is not included in 42.
Includes previously vacant House District 38 and Senate District 11, plus moves between chambers. This is district turnover, not a freshman count: Molly Buck is a returning former House member, and Nate Boulton previously served in the Senate. Incoming winners are not necessarily new to legislative service. Reconciled Nov 4, 3:38 PM CST; individual race source times remain unchanged.
This different measure counts people: 12 own-seat general losses, 3 own-seat primary losses, 3 departing unsuccessful candidates for other offices, 17 retirees or other non-candidates, and 3 federal-office winners. These categories do not overlap. Includes expected transitions, not a claim that all have already left office.
Excludes Charlie McClintock, whose Senate term continues; House-to-Senate winners Barb Kniff McCulla, Heather Matson and Timi Brown-Powers; and the already-vacant seats formerly held by Jon Dunwell and Julian Garrett. Daniel Gosa is called reelected by Decision Desk HQ and is not counted as departing.
All 150 legislative seats were compared with current official rosters: 99 sitting House members and 49 sitting senators. House District 38 and Senate District 11 are vacant, not defeated incumbents.
The own-seat list contains 12 named-source general-election defeats and 3 own-seat June primary defeats. No sitting member in this audit remains without a sourced own-seat outcome. Results can change; this is not a certified final list.
Retirements, campaign withdrawals and bids for a different office are distinct from losing reelection to the current seat. Current committee assignments exclude separate boards, commissions and former memberships.
