Election results
District boundaries have changed over time. Therefore, senators before 2021 may not represent the same constituency as today. From 1993 until 2003, the district covered part of Northwest Oregon; from 2003 through 2013, it covered a similar region as today plus northern parts of Jackson and Josephine counties; and from 2013 through 2023, it covered the same areas as previously mentioned while adding more territory in western Josephine county. The current district adds more of eastern Douglas County compared to the previous iteration while losing southern Douglas County as well as all parts of Jackson and Josephine counties previously included in the district.

The results are as follows:
