The Iran war's fuel-price shock is impacting key Senate battleground states, potentially causing a significant headache for Republicans defending their majority. Three of the top four weekly jumps in diesel prices hit key midterm Senate races: Texas, North Carolina, and Georgia, according to GasBuddy's Patrick De Haan. The cost of President Trump's unpopular war is also evident at the pump, with only 29% of Americans approving of the strikes and two-thirds expect gas prices to continue rising. The national average for regular gasoline hit $3.55 on Tuesday, up 61 cents from a month ago. Meanwhile, Democrats are criticizing President Trump for not addressing the rising gas prices, citing cost-of-living concerns.
