 About half of the portion of the district that had been in Benton County, Oregon was moved into the 4th district and portions of west-central Clackamas County were moved into the 3rd district.At the same time, small portions of northern Clackamas and southern Multnomah County that had previously been part of the 1st district were moved into the 5th district.The district is one of the few in the country that is not safe for either party on paper.
