McCain Ad Uses Biden's "Warning"

John McCain's campaign is out with a new ad this morning, one that uses Joe Biden's comments at a recent fundraiser about international tests that Barack Obama may face if elected. The ad begins with an announcer saying, "Listen to Joe Biden, talking about what electing Barack Obama will mean."

The ad the uses part of the audio of Biden's remarks at a recent fundraiser in Washington state over footage of world leaders like Hugo Chavez and Mahmoud Ahmadinejad. Biden: "Mark my words. It will not be six months before the world tests Barack Obama. The world is looking. We're going to have an international crisis ... to test the mettle of this guy. I guarantee you it's gonna happen." Announcer: "It doesn't have to happen. Vote McCain." Watch it:

Meanwhile, the Obama campaign is out with a new ad of its own, this one on taxes. The ad touts the tax calculator on Obama's Web site: "Not sure who to believe on taxes," the ad begins. "Try this. Enter your income, marital status, number of kids. Then click. A nurse earning sixty grand? You get a thousand bucks under Obama. Under McCain…just one-fifty. The independent Tax Policy Center says Obama offers middle class tax cuts three times as big as McCain's. Even leading conservatives say Obama's plan is better for the middle class. One point five million have tried it. You should too." Watch it:
