The Trump red diesel executive order, signed Monday in Grand Island, Nebraska, eases limits on tax-free red-dyed diesel as fuel prices put pressure on Republican candidates four weeks before the midterm elections.

What the order changes

Trump signed the order onstage before a crowd in Grand Island, a city in the solidly conservative south-central part of the state. A White House fact sheet spells out how the exemption works:

• •Diesel destined for off-road uses such as agriculture carries no federal or state excise taxes.
• •The fuel is dyed for law enforcement purposes.
• •Lifting the limits temporarily would ease cost pressures on the businesses that rely on diesel, according to the White House.

Who saves, by whose count

Trump announced the order on his trip to Nebraska, saying it would save farmers "millions" and drive down the cost of all goods, with four weeks to go until the elections. He put the typical trucker's savings at more than $100 per fill-up.

The math is contested. Patrick De Haan of GasBuddy said such an order could save money for on-road users, but not farmers, who already use red-dyed diesel. On X, he argued that supply, not taxes, is the problem.

The Nebraska stakes: Ricketts vs. Osborn

Trump told GOP Sen. Pete Ricketts and Gov. Jim Pillen that the move would guarantee their elections. Ricketts is running against an independent candidate backed by national Democrats; Pillen is seeking a second term.

Ricketts, a former governor, was appointed and later elected to the seat after Sen. Ben Sasse left in 2023 to run the University of Florida, and he is now running for his first full six-year term.

Ricketts's opponent is independent Dan Osborn, a former labor union chief who lost to Republican Sen. Deb Fischer by 7 percentage points in 2024. The race was initially not expected to be competitive, but it is now being watched by the national parties.

National Democrats back Osborn, yet he has refused to say which party he would caucus with should he win in November. Nebraska Democrats chose Cindy Burbank as their nominee, but she campaigned on ensuring no votes would be siphoned from Osborn and has since dropped out.

Diesel and beef prices shape the backdrop

The order lands with costs high on voters' minds. Diesel prices spiked in the aftermath of the Iran war, rattling voters and putting pressure on Republicans. Frustration with Trump's handling of the economy, persistently high fuel and grocery costs included, runs across the country and is a major issue for rural voters.

Beef is a parallel fight. The administration's plan to allow more imports of foreign beef has hit a particular nerve in agriculture-rich Nebraska. Trump wants lower beef prices for consumers, but ranchers rebelled against the import proposal, arguing it would undercut them.

Ricketts said the plan to import low-quality foreign beef is not helping Nebraska ranchers, and that he would advise the White House to change the policy and to look for longer-term steps to build the size of the herd and ultimately bring beef prices down for consumers.
