US oil firms drill, then ship it abroad anyway

Kind of kills the argument for more offshore drilling to increase US supply if they ship it abroad anyway. But hey, no one would have ever guessed that the oil companies are lying to us. Not to mention, I'm increasingly disturbed that Obama was right about the tire gauge thing. If we could get as much energy from simply filling our tires correctly, and offshore drilling could take a decade to realize its full potential (which isn't much), then why not just go to the tire-gauge route? The fact that McCain mocked it is increasingly disturbing since we now know that it works.
