On January 24, 2025, Dan Sullivan voted to confirm Pete Hegseth as secretary of defense in a 50-50 vote broken by the Vice President, so Hegseth would not have been confirmed without him. Hegseth's department has fought the war with Iran since February 28, 2026, and Sullivan has voted against every war powers resolution to end it, including one that failed 49 to 50 in September 2026. Gas in Alaska rose by more than a third in the war's first six months, and heating fuel in rural Alaska reached about $8 a gallon.
Sullivan also cast one of the votes that kept the global tariffs in a 49-49 vote, and he voted against extending the enhanced health insurance tax credits, after which Marketplace premium payments rose by more than half.
Dan Sullivan's Votes on War, Tariffs and Health Costs That Raised Prices
- Sullivan Cast the Vote That Confirmed the Defense Secretary Who Led the Iran War, and Alaska Fuel Prices Rose. On January 24, 2025, Dan Sullivan voted to confirm Pete Hegseth as secretary of defense; Vice President Vance broke a 50-50 tie, so the nomination would have failed without Sullivan's vote. Since the war Hegseth's department has fought began on February 28, 2026, Moody's economist Mark Zandi estimates it has cost the average household almost $2,000, "including $1,100 in higher energy prices, $540 in higher interest rates", and the national average for gasoline stood at $4.33 a gallon for gasoline, or 45% above its prewar level in October 2026.
- Sullivan Voted Against Ending U.S. Hostilities With Iran in March and September 2026. On March 4 and March 18, 2026, Sullivan voted no on motions to bring war powers resolutions on Iran to the floor (March 4, March 18); both failed 47 to 53. On September 24, 2026, he voted no on a concurrent resolution directing the removal of U.S. forces from hostilities with Iran, which failed 49 to 50. Through September 2026 he voted no on every Senate war powers vote on Iran, including ones that failed 49 to 50 in May and 49 to 50 in July. Over the same months, heating fuel prices in rural Alaska climbed to an average of $8 per gallon by August, up from $6.49 in January.
- Sullivan Cast One of the Votes That Kept the Global Tariffs in April 2025. On April 30, 2025, Sullivan voted no on ending the emergency behind the "reciprocal" tariffs; it failed 49 to 49, so his vote alone would have changed the result. On April 4, 2025 he had voted no on a budget amendment for "preventing Trump's tariffs from increasing the cost of groceries." New York Fed economists found tariffs had added 2.9 percentage points to goods price inflation by February 2026, and the Yale Budget Lab estimates the tariffs now in force cost households about $1,100 a year.
- Sullivan Voted Against Protecting Consumers From Tariff and War Price Increases in April 2026. On April 22, 2026, Sullivan voted no on waiving budget rules for an amendment for a reserve fund to protect consumers from price increases tied to tariffs and the Iran war; it failed 47 to 51. Tariffs then accounted for 0.2 to 0.4 percentage points of core inflation, the Minneapolis Fed found.
- Sullivan Voted Against an Amendment to Extend the Health Insurance Tax Credits in June 2025. On June 30, 2025, Sullivan voted no on waiving budget rules for an amendment to H.R. 1 to extend the enhanced premium tax credits, paid for by a higher rate on income over $10 million; all 53 Republicans voted no and it failed 47 to 53. The credits expired at the end of 2025, and enrollees' premium payments rose 58%, from $113 to $178 a month on average in 2026.
- Sullivan Voted Against a Rule to Block Bills That Raise Electricity Bills in February 2025. On February 20, 2025, Sullivan voted no on a point of order against legislation that would raise energy costs for Americans, "including higher monthly electricity bills"; it failed 47 to 53. The law that followed ends the clean-energy tax credits, and Energy Innovation projects its energy provisions will mean "760,000 lost jobs by 2030" and higher energy costs nationally.
- Sullivan Backed the Attack on Iran in February 2026 and Called the War Temporary in October. On February 28, 2026, Alaska Public Media reported that U.S. Sen. Dan Sullivan said he supports the U.S. attack on Iran. At a rally in Wasilla on October 13, 2026, he said: "Ladies and gentlemen, the conflict in the Middle East is temporary." For households that heat with oil, the Energy Information Administration expected winter heating costs to be 21% higher because of the war's effect on fuel prices.
What the War, Tariffs and Premiums Dan Sullivan Backed Cost Alaska Families
- Gas prices. Regular gasoline in Alaska rose from $3.50 to $4.83 a gallon, or 38.1 percent, between February 18 and August 20, 2026, according to AAA data compiled by Visual Capitalist.
- Rural heating fuel. Heating fuel in rural Alaska, where many villages depend on fuel delivered by barge or plane, averaged $8 per gallon by August 2026, up from $6.49 in January.
- Freight. Alaska Marine Lines, which barges freight to Alaska, said in April 2026 that its fuel related surcharge will increase from 11 to 18.5 percent, a cost carried into the price of groceries and goods shipped north.
- Tariffs. Executive tariffs have cost Alaska the equivalent to $420 per Alaska household since January 2025.
