The rise in gasoline prices and dissatisfaction with the Iran war will affect Trump's midterm elections In the week leading up to the American midterm elections, the rise in gasoline prices and the economic consequences of the Iran war have become one of the axes of voter dissatisfaction. The average price of a liter of gasoline in the United States is $1.29 more than before the start of the war, and some voters criticize the rise in the cost of living and the start of unnecessary wars. Despite these complaints, Trump continues to promise that once the war is over, the price of oil and gasoline will drop sharply.
