Incidentally, it was Barack Obama's birthday today and the RNC put this up on their website:

Well, it turns out that Obama was right. Time is reporting that
[E]fficiency experts say that keeping tires inflated can improve gas mileage 3%, and regular maintenance can add another 4%. Many drivers already follow their advice, but if everyone did, we could immediately reduce demand several percentage points.
By the Bush Administration's estimates (probably on the extremely optimistic side), expanding off-shore drilling would provide us with only 1% of our oil demand in 20 years.
This is yet another demonstration that if elections were merely about facts, this thing would have been over a long time ago.
