About this page

Seats, incumbents and results are derived from the Senate's service records (via the congress-legislators dataset): the seats on a year's ballot are the class whose terms end the following January, plus any seat held by appointment pending a special election, and a result is recorded when the winner is sworn in. Incumbent status and candidates for the next election come from FEC candidate filings; a seat is listed as open when the FEC tags its candidates as running for a seat with no incumbent. Election day is the Tuesday after the first Monday in November. See every cycle since 1990, the seniority list and the voting analysis.
