Oregon voters are heading to the polls on Tuesday, May 21, 2026, for primary elections that will determine the nominees for the upcoming midterm elections. The state, a traditional Democratic stronghold, is witnessing a particularly competitive race for governor, with incumbent Tina Kotek facing numerous challengers in her bid for a second term.

The primaries are crucial for winnowing down the nearly two dozen candidates seeking to represent both major parties in the November general election. This year's contest for the state's top executive office is exceptionally crowded, with a substantial number of contenders vying for nomination.

In the Democratic primary, Governor Kotek is the frontrunner, but she faces competition from nine other candidates, including a children's book author, the head of an Indigenous nonprofit, and an inventor focused on water scarcity solutions. On the Republican side, the field is even larger, with State Senator Christine Drazan emerging as a leading contender. Drazan, who previously ran against Kotek in 2022, has voiced criticism of former President Donald Trump's trade policies while supporting his immigration stances. Another notable Republican candidate is former NBA player Chris Dudley, who was the party's nominee in 2010 and achieved one of the narrowest losing margins for a Republican gubernatorial candidate in decades. State Representative Ed Diehl is also seeking the nomination, aiming to leverage his opposition to a recent gas tax increase.

Opinion polls indicate Drazan holds a significant lead in the Republican gubernatorial primary, with 35 percent support. Governor Kotek is widely expected to secure an easy victory in the Democratic primary, with her opponents not registering significant polling numbers.

Beyond the gubernatorial race, Oregon voters will also decide on a referendum concerning the state's fuel tax. The vote on whether to repeal the tax comes as consumers face rising gasoline prices, partly attributed to global geopolitical tensions. This economic question adds another layer of significance to Tuesday's primaries, potentially serving as an economic bellwether.

Polls are scheduled to open at 7 a.m. Pacific Time (15:00 GMT) and will close at 8 p.m. (4:00 GMT). The outcomes of these primaries will set the stage for the November elections, shaping the political landscape of Oregon for the coming years.

The large number of candidates for governor reflects the diverse political currents within Oregon, even within its generally liberal political climate. The Republican primary, in particular, showcases a range of perspectives, from established state politicians to figures from the sports world, each seeking to capture the party's nomination.

The fuel tax referendum could have tangible impacts on state revenue and transportation funding, making it a focal point for many voters concerned about economic pressures. Its inclusion on the primary ballot ensures that this fiscal issue receives significant attention ahead of the general election.
