Joe the Plumber has helped give the McCain campaign its closing economic message. Now Joe the Senator has pitched in by helping frame the national security message. And the McCain campaign needs to get the national security issue back front and center--at least close to the front and near the center--in the final two weeks. Here's the ad, simply quoting Joe Biden, speaking at a fundraiser in Seattle Sunday:

Mark my words...It will not be six months before the world tests Barack Obama...Remember I said it standing here if you don't remember anything else I said. Watch, we're gonna have an international crisis, a generated crisis, to test the mettle of this guy....And he's gonna need help....Because it's not gonna be apparent initially, it's not gonna be apparent that we're right.
