Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in Colorado in 2024. Information below was calculated on May 8, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
There were 83 legislative seats up for election this year in Colorado's legislature—18 in the Senate and 65 in the House. There were 25 total contested primaries in 2024 (11 Democratic and 14 Republican) out of a possible 166. This rate of 15.1% was the highest since Ballotpedia began tracking this figure in 2010.
The 26 Colorado legislators not running for re-election in 2024 aligned with the average for elections from 2010-2022 (25.6). The retirements in 2024 were the third-most this decade behind 2022 (33) and 2018 (27).
Colorado legislators are limited to serving eight years in the Senate and eight years in the House. Four members of the House were term-limited in 2024.

- ↑ 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.
