Oregon's 19th Senate district

District map

District 19 of the Oregon State Senate comprises parts of Clackamas, Multnomah, and Washington counties. It is currently represented by Democrat Rob Wagner of Lake Oswego.

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 the central Willamette Valley, and from 2003 until 2013 it covered a slightly different area in the Portland metropolitan area.
