Background Democrats had held the Oregon Senate since 2002 and the chamber was not considered competitive in 2020.
Electoral system Members of the Oregon State Senate are elected from single-member districts by first-past-the-post voting to four-year terms with staggered elections. Contested nominations of the Democratic and Republican parties for each district were determined by an open primary election. Minor-party and independent candidates were nominated by petition, and write-in candidates had to file a request with the Secretary of State's office for votes for them to be counted.
