Senate candidates in Maine, New Hampshire, and Alaska are focusing on the rising cost of residential heating oil as winter and the November midterm elections approach. According to the Energy Information Administration (EIA), the national average for heating oil has reached $6.23 per gallon, an increase from approximately $3.60 a year ago. In Maine, where half of all households use fuel oil for heat, the average cost to heat a home this winter is projected to exceed $4,000.
The price surge follows global supply disruptions linked to the U.S.-Iran war, which began in February 2026, and the ongoing Russia-Ukraine conflict. The cost of residential heating oil rose from an average of less than $4 per gallon before the war with Iran to more than $6 currently. According to Decision Desk HQ, Democrats are narrowly favored to flip the Senate as Republicans address voter concerns regarding these costs.
In Maine, Democratic challenger Troy Jackson has attributed high costs to the war in Iran and criticized incumbent Sen. Susan Collins (R-ME) for initially backing the conflict. Collins has since opposed the war and successfully urged the administration to release 315,000 barrels of oil from the Northeast Home Heating Oil Reserve. In New Hampshire, Rep. Chris Pappas (D) has called for increased funding for the Low-Income Home Energy Assistance Program (LIHEAP), a measure his opponent, former Sen. John Sununu (R), also supports. In Alaska, Sen. Dan Sullivan (R) is facing former Rep. Mary Peltola (D), who argues Alaskans may be forced to choose between food and fuel.
The political impact is centered on the 2026 midterms, where control of the U.S. Senate may be determined by these results. A shift in representation could lead to different legislative priorities; Democrats like Troy Jackson and Mary Peltola advocate for clean energy projects and electrification to move away from fossil fuel price cycles, while Republicans like Susan Collins and Dan Sullivan emphasize increased domestic drilling, pipeline expansion, and diesel export moratoriums to stabilize the current market. A change in Senate control would also influence the future of programs like LIHEAP, which assists nearly 6 million homes nationwide.
The immediate relief efforts involve the federal release of 315,000 barrels of heating oil, though energy analysts, such as William O’Neil of S&P Global Energy, stated the volume may be too small relative to total consumption to significantly lower market prices. Voters will cast their ballots in these key Senate races on Tuesday, November 3, 2026. Following the election, the new Congress will likely face deadlines for energy permitting reforms and further funding authorizations for federal heating assistance programs.
