McCain should immediately call for a special session, and the President should recall Congress in response...
That would be an awesome move!!! The 'Rats and MSM would howl and rage over it, but the example of Harry Truman could be brought up endlessly. The Demagogues would be on the defensive and it would be hard for them to change the dynamic of the situation (they would have to actually DO something significant and dramatic on energy to really convince anyone except the cultists that they were serious).
