Obama Ad: Energy As "National Priority"

About a week ago, as Ben Smith reports, the Obama campaign started airing a new ad centered on energy. Only they didn't tell the press. So while this spot looks like the second in the Obama camp's series of energy spots criticizing John McCain – after an ad unveiled yesterday saying McCain is in the "pocket" of big oil – it's really the first. Got that?

"John McCain. He's been in Washington for 26 years," an announcer says in the newly-unearthed spot, "National Priority." "And as gas prices soared and dependence on oil exploded, McCain was voting against alternative energy, against higher mileage standards."

The spot then shifts to a focus on Obama. Says the announcer:

"Barack Obama. He'll make energy independence an urgent national priority, raise mileage standards, fast-track technology for alternative fuels. A thousand dollar tax cut to help families as we break the grip of foreign oil. A real plan, and new energy."

The Obama campaign tells CBS News that the spot is airing in "battleground states." Watch it below:
