Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in Idaho in 2024. Information below was calculated on April 15, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
There were 105 state legislative seats up for election this year in Idaho. Across those, six incumbents (two Democrats and four Republicans) did not file to run for re-election. That's the fewest number of retirements since at least 2010. From 2010 to 2022, the average number of retirements per cycle was 19. In 2022, 31 incumbents (six Democrats and 25 Republicans) did not run for re-election.
The total number of contested primaries (with more than one candidate) was higher than the average for election cycles from 2010 to 2022. In 2024, there were 56 contested primaries (four Democratic and 52 Republican) out of a possible 210, a rate of 26.7%. The average for the previous seven election cycles was 23.8%. In 2022, the decade-high, there were 71 contested primaries (all Republican) for a rate of 33.8%.
All 35 Senate seats and all 70 House seats were up for election in 2024.

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.
