Post-filing deadline analysis
The following analysis covers all state legislative districts up for election in Oregon in 2024. Information below was calculated on May 16, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
There were 75 state legislative seats up for election in Oregon in 2024. Across those, 14 incumbents (six Democrats, seven Republicans, and one Independent) did not file to run for re-election. That was just over the average number of retirements since Ballotpedia began tracking this data in 2010 (13.9). In 2022, 24 incumbents did not run for re-election (15 Democrats and 9 Republicans).
Eleven incumbents out of 61 running faced primary challengers. That was the most since 2010, and the highest percentage of incumbents in contested primaries during that span (18%). The next closest year was 2022 with 9 contested incumbents (17.6% of 51 incumbents) running in contested primaries.
The total number of contested primaries (with more than one candidate) was 27 (12 Democratic and 15 Republican). This was higher than the average number of contested primaries from 2010-2022 (23.9), and the third highest year overall after 2022 (37) and 2020 (33). This means 18% of possible primaries in Oregon in 2024 were contested, the third highest figure since 2010. The year with the highest percentage of contested primaries was 2022 (24.7%), followed closely by 2020 (22.0%).
Oregon had a Democratic trifecta, meaning the Democratic Party controlled the governorship and both chambers of the state legislature. As of May 16, 2024, there were 23 Republican trifectas, 17 Democratic trifectas, and 10 divided governments where neither party held trifecta control.

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.
