While I share your sentiments about drilling for oil, if a trustworthy candidate had said that, I would believe him. But, Mac has more lies than Carter has pills, he's made a history of betrayal and if you want to know how someone will behave in the future, study his past.
IOW, find yourself a good third party candidate. The Presidency is lost no matter who gets in. We might at least salvage the future by sending the GOP a message by not rubber-stamping their boy.
And we can start taking it back as early as 2010. The economy and state of the Union should be a real blunt trauma case by then.
