"drilling would help lower gas prices today"

The announcement of drilling will bring down the price of crude due to the anticipation of more oil available in the future.

"In a dramatic move yesterday President Bush removed the executive-branch moratorium on offshore drilling. Today, at a news conference, Bush repeated his new position, and slammed the Democratic Congress for not removing the congressional moratorium on the Outer Continental Shelf and elsewhere. Crude-oil futures for August delivery plunged $9.26, or 6.3 percent, almost immediately as Bush was speaking, bringing the barrel price down to $136.
 Democrats keep saying that it will take 10 years or longer to produce oil from the offshore areas. And they say that oil prices won't decline for at least that long. And they, along with Obama and McCain, bash so-called oil speculators. And today we had a real-world example as to why they are wrong. All of them. Reid, Pelosi, Obama, McCain — all of them."
