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 parts of Southern Oregon; from 2003 until 2013, it shifted to its current location and covered more of inner northeast Portland; and from 2013 until 2023, it covered more land east of I-205.

The current district is similar to its previous iterations, but does not cover any land east of I=205 not in the Lents neighborhood and extends south to the border of Multnomah County by adding the Brentwood-Darlington neighborhood.
