The ask lands on Capitol Hill, not at a pump. A gas tax suspension requires an act of Congress — Article I authority — and even a full waiver of the federal 18.4-cent-per-gallon excise tax would not offset the price spike driven by the war. That's the tell: this is a blame-shift play, not an energy policy. If Congress moves, Trump claims credit. If Congress stalls, he has a midterm villain. The number that matters isn't 18 cents — it's however many swing-district House members are now on the record.
