This page focuses on the Democratic primaries that will take place in Oregon on May 19, 2026.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Oregon law allows parties to decide whether unaffiliated voters can vote in their primaries. As of December 2025, both major parties utilized a closed primary process where only registered party members may participate.[1]
For information about which offices are nominated via primary election, see this article.
