I wouldn't put it past Obama to do just that. And maybe have the EPA shut down a few refineries just for giggles.
And just HOW would the "Big Bad 'Bama" do that?
Everyone seems to think that the President, PERSONALLY (and no matter who the President is) has a big valve in the Oval Office that he can turn to control the supply of fuel and crude oil.
Because there's no state agency that controlls production, as there is in Russia and Venezuela or the other OPEC nations, the government can't arbitrarily screw with production to produce a short-term event.
If EPA tried to shut down refineries on an arbitrary whim, the Federal court injunction stopping that action would take maybe 8 hours to be issued. It's happened before, in the 1970s, when Carter's Energy Czar (IIRC it was him) tried to do a massive quasi-nationalization of production, storage, and refining in response to the OPEC embargos.
It didn't work.
