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.

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.

In this election, these seats were represented by 35 Democrats and 25 Republicans.
