This is a dated current-member snapshot. Membership follows the active term identified by the official chamber directory. A candidate list or vote lead does not establish a serving member. This view does not refresh automatically.
This serving 69th Legislature snapshot was checked November 6, 2026 (America/Chicago). It contains 100 House members and 50 senators, with no vacant seats. Names, party labels and supplied profile URLs reconcile exactly between the official session-membership API and the Legislature’s independent profile data.
The live API marks the future 2027 session active before its January 4, 2027 start and overwrites some current members’ chamber and district fields with incoming assignments. The official 2025 Session Laws membership tables control serving chamber and district. Thirteen premature assignments are corrected to their serving seats; each affected row links to this evidence. No incoming election winner is substituted for a current member.
For example, Amy Regier remains the serving House District 6 representative, David Bedey House District 86, Kelly Kortum House District 64, and Janet Ellis Senate District 41. Their future API chamber/district assignments are retained only in provenance, not published as current service.
Four explicit former House members are excluded: Ron Marshall, Marta Bertoglio, Ed Stafman and Bill Mercer. Current replacements Terry Nelson and Mark Reinschmidt are footnoted in the official session-laws roster. Stacy Zinn’s service is independently evidenced by official county swearing-in minutes; Katie Fire Thunder’s 69th-Legislature service is evidenced by the January 2026 official committee minutes and session membership.
MCA 5-2-102 begins regular legislative service on the first Monday of January after election; the next regular transition is January 4, 2027. Its separate exception for a senator elected to fill a vacancy is not treated as the regular-term rule. Future term dates in live profile fields do not end an incumbent’s current service.
