Oregon Voters Reject Gas Tax Hike Amid Iran War Fuel Crisis

Oregon voters delivered a decisive rebuke to Democratic lawmakers on Tuesday, rejecting Measure 120 — a gas tax and transportation fee increase — by a margin of approximately 82% to 18%, according to initial election results. The defeat came as the ongoing Iran war pushed Oregon’s average gas price to $5.34 per gallon, more than 80 cents above the national average and $1.38 higher than a year ago.

What Measure 120 Would Have Done

The measure, passed by the Democratic-controlled legislature during a special session last fall and signed by Gov. Tina Kotek, would have raised Oregon’s gas tax from 40 cents to 46 cents per gallon, doubled most vehicle registration fees, raised title fees from $77 to $216, and doubled the 0.1% payroll tax for public transit through 2028. The Associated Press reported that the package was designed to address a growing transportation funding crisis as more drivers switch to electric and fuel-efficient vehicles, reducing gas tax revenue.

Why It Failed

Republicans launched a successful referendum campaign, gathering more than 250,000 signatures — over three times the 78,000 required — to place the measure on the ballot. The timing proved catastrophic for supporters. The Iran war, which began on February 28 when President Donald Trump ordered an attack on Iran, has effectively closed the Strait of Hormuz, disrupting 20% of global oil supplies. According to Wikipedia, the International Energy Agency has called this the “largest supply disruption in the history of the global oil market.”

Republican State Sen. Bruce Starr, who led the referendum campaign, told the AP: “I was not surprised at all that Oregonians have rejected a completely unpopular tax increase. Oregon voters will not be ignored. Oregon taxpayers will not be ignored.”

Chris Koski, a professor of political science at Reed College, noted the impossible timing: “It’s difficult to imagine a worse situation for a gas tax increase than right now in American politics,” he told the AP.

Voter Sentiment on the Ground

Even in Portland, Oregon’s progressive hub, voters were divided. David Trujillo, a 25-year-old who voted for Kotek in the primary, said he opposed the gas tax increase. “I think at the moment, with the gas prices being up and with the war that is occurring, it’s very difficult for folks to get around,” he told the AP. “If the gas prices were to rise, I think that would be a huge barrier for more of our community members.”

Michael Burch, a 76-year-old retiree from Portland, echoed the sentiment: “I’m sick and tired of taxes. Gas is certainly dampening the spirits and the coffers of folks that aren’t as well off.”

Broader Political Implications

The defeat complicates national Democrats’ midterm election strategy, which has centered on affordability and lowering the cost of living. Republicans successfully framed the tax increase as adding to the burden on households already squeezed by inflation and war-driven fuel prices. As the Oregon Capital Chronicle reported, Oregon voters have rejected gas tax hike proposals more than five times since 1928.

Democratic State Rep. Paul Evans acknowledged the messaging failure: “When anything is reduced to, ‘Do you want a tax or not?’ Most people are going to say no. The messaging got away from us, and it became focused upon the price instead of the value.”

What’s Next for Oregon’s Transportation

The defeat leaves Oregon facing a significant transportation funding shortfall. The Oregon Department of Transportation had already stopped filling more than 100 positions. Without the $4.3 billion the measure would have raised over a decade, layoffs, delayed highway maintenance, and transit service cuts are possible.

Gov. Kotek has convened a 12-member workgroup of transportation and business experts tasked with finding a long-term solution, with recommendations due by the end of 2026. Legislative action is not expected until the 2027 session.

Erin Good, a spokesperson for the Association of Oregon Counties, warned: “Without sustainable revenue, counties will face increasingly difficult decisions that directly impact road user safety and increase long-term costs to the public.”

The Iran War Factor

The same day as the Oregon vote, the U.S. Senate advanced a bill aimed at ending U.S. military involvement in Iran by a 50-47 vote, with Republican Sen. Bill Cassidy of Louisiana flipping to support the measure after losing his primary. President Trump has proposed suspending the federal 18-cent gas tax, though that would require congressional approval.

Nationally, gas prices topped $4.50 per gallon on May 8 and have risen approximately $1.16 per gallon since the war began. The crisis has triggered global fuel shortages, panic buying, airline disruptions — including Spirit Airlines ceasing operations on May 2 — and fears of stagflation and recession.

Looking Ahead

With Measure 120 defeated, Oregon lawmakers must find alternative ways to fund road maintenance and transit. The Kotek workgroup’s recommendations will shape the debate, but any new proposal will face the same headwinds: a historically tax-averse electorate, soaring fuel prices, and a transportation system in need of sustainable funding. For now, Oregonians have sent a clear message that higher taxes at the pump are not the answer — especially in the midst of a global energy crisis.
