Diesel Prices Reach Record High, Put GOP in a Bind Over Trump‑Iran War Ahead of 2026 Elections

Diesel has surged to a new all-time high (about $5.88 a gallon), fueling GOP worries that fuel and broader inflation tied to Trump’s Iran war could hurt their 2026 midterm prospects. Insiders say candidates can’t distance themselves from the president, while officials like Transportation Secretary Sean Duffy frame the spike as driven by global markets (e.g., Russia/Ukraine) rather than domestic policy. The story also notes that higher diesel costs ripple into groceries and overall living costs, adding pressure on voters as campaigns gear up for the election.
