A Newsweek article by Joe Edwards reports GasBuddy analyst Patrick De Haan's projection that the national average gas price will be $3.59 to $3.69 per gallon over Thanksgiving, with diesel at $5.85 to $5.95. De Haan attributes the falling prices chiefly to the switch to cheaper winter gasoline and seasonal demand drops, saying the midterm elections had nothing to do with it.
