I don't understand where you think you have a point. In both instances the assertion remains identical, i.e. the POTUS is not the one who sets the price of petrol. POTUS neither makes it cheap nor makes it expensive. Unregulated petrol distributors on the other hand literally do set the price with no regard to real cost of a barrel of crude; it is based entirely on supply/demand and market projections, and usually by OPEC suppliers.
