Election results

District boundaries have changed over time. Therefore, senators before 2013 may not represent the same constituency as today. From 1993 until 2003, the district covered parts of Multnomah County; from 2003 until 2013, it shifted to cover south, east, and north Salem apart from the downtown as well as Woodburn; and from 2013 until 2023, it lost much of south Salem but added the downtown core.

The current district is similar to its previous iterations, adding Keizer and Saint Louis while losing all of south Salem and the southern part of downtown.
