How this page is built

Races are listed by state. Holders come from the audited snapshot of who is in office; the date each took the seat and the end of each term come from the term records; every last result is the race as recorded here, linked. Nothing on this page names a candidate, and no seat is rated. Once certified results are published they replace this page at the same address.
