McCain Ad Uses Biden's Words Against Obama

The McCain campaign's newest television advertisement, released Friday morning, goes straight after Barack Obama's readiness to handle an international crisis by using his running mate's words against him.

Titled "Ladies and Gentlemen," the spot juxtaposes Joe Biden's rather boneheaded (but out of context) statement that Obama will be tested within six months in office with a series of frightening shots of terrorists and hostile foreign leaders.

"It doesn't have to happen," says the announcer. "Vote McCain."

In past elections this line of attack would likely be a far more dominant narrative. But it is testament to just how prevalent economic concerns are -- and just how strong of a debate performance Obama had -- that questions about his foreign policy readiness haven't had their traditional affect.
