Democrats are poised to take control of Congress after midterms in which voter anger over fuel costs from the Iran war was a major factor. Brent has fallen to near $95 from about $110 earlier in the war, but gasoline averages $4.12 and diesel is about $2.50 above a year ago.
Retail fuel prices track a complex international crude and refined-product market, so a new Congress is unlikely to move them quickly. Diesel stays expensive for trucking and feed transport costs while Hormuz disruption persists.
