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.
