A recorded vote is a documented position on that question on that day. It is not evidence of what the member sought or conceded.
Evidence for this page
Every row comes from the Oregon Legislative Information System’s official rosters and committee memberships, observed 2026-09-01. Roster codes recorded: Rep Gamba. The official page link is the roster's own website field.
Rosters are per session; exact seating and departure dates within a session, and the reasons for any replacement, are in the chamber journals and are not claimed here.
Nothing on this page describes campaign finance, private employment, or personal life. Those are outside the institutional record this site publishes. Cite as: Oregon Governance Atlas, “Mark Gamba,” edition dated August 31, 2026. Regenerated 2026-09-04.
