Effectiveness figures follow the published formula. Campaign-finance figures are not included in comparisons.

Read with care. This is a transparent count of how far a member's own bills went, not a judgment of the member's work. It does not weigh a bill's importance, and it misses amendments, conference work, constituent service and blocking bad bills. Leadership files many shell bills that never move; members elected mid-term had less time; coauthors are read from action text and may be incomplete. Data: Open States roll calls and actions (copied Oct. 1, 2026); official records are on oklegislature.gov.
