Sure, and blame Obama for bad tomatoes, too

A new television ad by Sen. John McCain's campaign seeks to exploit anger over gas prices by directing it toward his opponent.

"Gas prices: four dollars, five dollars, no end in sight," says the narrator in the advertisement , which the McCain campaign released July 21, 2008. "Because some in Washington are still saying no to drilling in America."

Oil drilling goes on all the time in America. What Sen. Barack Obama and others oppose is certain new drilling off the coasts. But let's leave that aside.

Some in Washington, the ad continues, say "no to independence from foreign oil." Almost no one opposes the notion of independence from foreign oil. The dispute is over how to get there. But let's leave that aside as well.

The ad culminates with this question: "Who can you thank for rising prices at the pump?" Then we hear a chant familiar to anyone who has watched a fevered Obama rally: "O-ba-ma! O-ba-ma! O-ba-ma!" So the central claim of the ad, and the one we decided to check, is that Obama is to blame for rising gas prices.

In its news release announcing the ad, the McCain campaign cited everything from Obama's criticism of McCain's electric car contest to Obama's reservations about nuclear power. But in our view those things don't sufficiently back up McCain's sweeping contention that the junior senator from Illinois is to blame for rising gas prices.

The main implication of the ad is that the ban on some offshore drilling — a ban that McCain has long opposed, more explicitly lately than in the past — has contributed to rising prices, and since Obama supports it, it is fair to blame him for it.

The last part is highly dubious. Obama has only been in the U.S. Senate since 2005, and the congressional moratorium prohibiting oil and gas leasing on most of the outer continental shelf dates to 1982.

Granted, Congress has renewed it every year since. But there was also a presidential order banning oil exploration off the coasts from 1990, when the first President Bush issued it, until July 14, 2008, when his son lifted it.

So even if the ban on offshore drilling contributed to "rising prices at the pump," it would have done so regardless of how Obama felt about it, at least until the very recent past.

Now, has the ban in fact contributed to rising prices at the pump? Probably so, though it's impossible to say how much.

stated on April 26, 2007 in Stratham, N.H.

"(McCain) was opposed to ethanol. Now he's for it."

Currently, drilling is allowed in about 15 percent of federally controlled waters, and those areas are the source of more than one-quarter of the oil produced in the United States, according to Ron Planting, an economist at the American Petroleum Institute. Domestic production accounts for about a quarter of the oil the country consumes, Planting said.

It is not likely that all the other offshore areas currently off limits would be as productive as the Gulf of Mexico, where most of today's offshore drilling takes place, Planting said.

"The only thing we can say is directional," Planting said. "We'd have more supply (if the moratorium hadn't been in place)] and historically more supply has downward pressure on prices."

But that's really a peripheral issue. Regardless of how the moratorium has affected prices over the years, Obama has not been a key force behind it until very recently.

True, he vows to be just that in the future. But how lifting the moratorium would affect future prices is a separate question, (and a tricky one, as we explain here ).

What the ad pins on Obama — and others who are "saying no to (new offshore) drilling in America" — are the price increases the country is currently enduring. That saddles the Illinois senator with a lot more influence than he has had. If one were to line up all the leaders in Washington who share some responsibility for the offshore drilling moratorium — the first President Bush, the Republican leadership of Congress, the Democratic leadership of Congress, the Florida delegation — there would be quite a few people ahead of Obama. We find McCain's claim to be False.
