What “missed” means

A “Not Voting” entry on a roll call means the member was absent or chose not to vote. It includes both excused absences (illness, family emergency, official travel) and unexcused. Attendance can dip during recesses and around major personal events; over a 30-day window it’s a useful but imperfect indicator. A persistent pattern across longer windows is more telling — see each member’s full record on their profile page.
