Vote YES in Nov 2020 - Amend OR Constitution to End Gerrymandering in Portland
At this point (July 2020) we don't know if this will be on the ballot in Nov 2020 or not, but signs are looking good.
This measure will replace the current system of redrawing political boundaries in Oregon by the legislature to a 12 member citizens committee, composed of 4 Democrats, 4 Republicans, and 4 individuals not associated with either of the two major parties; thereby allowing individuals who are either not registered with a major party or who are registered with a minor party to be part of deciding how political boundaries are drawn. That process currently excludes those groups because the redrawing decisions are made by the legislature which contains not a single non-affiliated voter or minor party member.
