As a result of the elections, the Democratic Party expanded its advantage in both houses of the state legislature. The party gained one seat in the Oregon State Senate and three seats in the Oregon House of Representatives, bringing its advantage over the Republican Party to 18–12 and 38–22, respectively. These gains gave the Democratic Party a 3/5 (or 60%) supermajority in both chambers for the 80th Oregon Legislative Assembly.^[1]

The 30 members of the Oregon State Senate are elected to four-year terms, and only half of those seats (15) are up for election every two years. In addition to these 15 regular elections, there were two special elections to determine who would complete the four-year terms of senators who were replaced during the first half of their term. These 17 seats up for election were represented by 10 Democrats and seven Republicans. The Democrats decreased their advantage over Republicans from 18–12 to 17–13 in the 2016 election.
