Oregon voters face crowded primary for governor and fuel tax referendum.

Oregon is preparing for a crowded primary election that will determine the state's nominees for the upcoming midterm contests. Nearly two dozen candidates are vying to unseat incumbent Governor Tina Kotek, who seeks a second term in office. Although the state has long leaned heavily toward Democratic candidates since the 1980s, the competition to retain political power remains fierce even in this blue stronghold.

Voters will cast their ballots on Tuesday to select party nominees for the November general election. This vote also serves as an economic barometer, featuring a referendum that could eliminate a state fuel tax. This measure is particularly significant as regional tensions involving the US and Israel regarding Iran continue to strain consumer prices at the gas pump.

Polls open at 7am Pacific Time and close at 8pm on Tuesday. In the gubernatorial race, Governor Kotek faces nine Democratic challengers, including a children's book author, an Indigenous nonprofit leader, and an inventor focused on water security. She currently holds a significant lead in the polls and is expected to secure the Democratic nomination easily.

The Republican field is even more competitive, with State Senator Christine Drazan currently leading with 35 percent support. Drazan previously challenged Kotek in 2022 and supports President Trump's immigration stance despite criticizing his tariff policies. Other Republican contenders include former NBA player Chris Dudley, who ran in 2010, and State Representative Ed Diehl, who aims to leverage his success in blocking previous tax increases.

US Senator Jeff Merkley is also seeking re-election for a fourth consecutive term. The 69-year-old legislator, who began his career in affordable housing, faces eight rivals including seven Republicans and one Democrat. His seat is considered relatively safe, and he is expected to win the Democratic primary before heading to the general election.

Additionally, all six of Oregon's members of the US House of Representatives will participate in the primary process. Five of these representatives are Democrats running for re-election. These races highlight the diverse political landscape and the intense scrutiny facing state officials in Oregon.

Cliff Bentz, the Republican incumbent for Oregon's second congressional district, faces his electorate in a sprawling race covering the entire eastern half of the state. On Tuesday, voters will also select party nominees for state Senate and House seats, while simultaneously choosing a nonpartisan commissioner to lead the state Bureau of Labor and Industries.

Oregon operates as a closed primary state, restricting nominees to candidates from the party with which a voter is registered. Despite the state's generally left-leaning political climate, which often propels Democratic frontrunners in statewide contests, the election landscape remains susceptible to unexpected outcomes. State voter rolls reveal that fewer than 25 percent of Oregonians are registered Republicans, compared to 32 percent for Democrats, with the largest segment of the electorate identifying as non-affiliated. Consequently, primary victories in right-leaning jurisdictions like the second district may serve as a barometer for how closely local Republican politicians intend to align with President Trump.

A significant issue on Tuesday's ballot is a referendum seeking to repeal a recent gas tax increase. The state legislature approved the tax hike to fund road maintenance and bolster the transportation budget. However, as regional conflicts involving Iran drive gas prices in Oregon up by an average of 80 cents, Republicans are leveraging the referendum to appeal directly to voter concerns regarding the cost of living.

Beyond these statewide contests, nearly 100 local measures will appear on ballots across various counties, primarily focusing on funding for fire departments, schools, and libraries. Preliminary results are anticipated on Tuesday evening shortly after polls close at 8 p.m. local time. Nevertheless, the counting process will extend beyond election day as mail-in and provisional ballots are processed, meaning some races may not be officially decided until several days later.
