Obama goes up with his second national security ad in two days, a spot that highlights our changing security imperatives in a way designed to dovetail with today's "21st Century Threats" summit...
There's no mention of Iraq in the ad, just as in yesterday's spot. But the ad underscores the intensity and seriousness of purpose of the Obama camp's push on national security in advance of his tour abroad next week.
"New leadership, for a changing world," says the ad, putting Obama's change message in a national security context in hopes of defusing attacks on his foreign policy readiness.
