Footnotes
- ↑ Ballotpedia defines an incumbent as retiring if the incumbent did not file for office or filed for office but withdrew, was disqualified, or otherwise left a race in a manner other than losing the primary, primary runoff, or convention. If an incumbent runs as a write-in candidate, Ballotpedia does not consider them to be retiring. If an incumbent runs in the same chamber for a different seat, Ballotpedia does not consider them to be retiring.
- ↑ Ballotpedia defines a seat as open if the incumbent did not file to run for re-election or filed but withdrew and did not appear on any ballot for his or her seat. If the incumbent withdrew from or did not participate in the primary but later chose to seek re-election to his or her seat as a third party or independent candidate, the seat would not be counted as open. If the incumbent retired or ran for a different seat in the same chamber, his or her original seat would be counted as open unless another incumbent from the same chamber filed to run for that seat, in which case it would not be counted as open due to the presence of an incumbent.
