That's because the government doesn't allow gas stations to lower gas for a "gas war."
So I hope the Koch brothers don't get in trouble for this:
Koch Brothers Deliver Cheap Gas to St. Louis RUSH: In St. Louis: 'The Gas Can Man,' a creation of the conservative lobbying group Americans for Prosperity, will be at the Alcorn Service Station at 5470 S. Lindbergh Blvd. on Friday, offering gasoline at $1.84 per gallon (limit, 10 gallons) to the first 150 vehicles that arrive starting at 8 a.m," starting tomorrow morning. A buck eighty-four is what it was when Obama took office. This lobbying group is the Koch brothers. The Koch brothers paying for a-buck-eighty-four-a-gallon gasoline, St. Louis, eight o'clock tomorrow morning. Ha-ha-ha.
