Vice President Joseph Biden trumpeted President Obama's foreign-policy credentials Thursday night during a speech in New York, but his main intention seemed to be slamming presumptive Republican nominee Mitt Romney. Biden shifted the battle from jobs and taxes to foreign relations and said Romney would leave American troops stranded in Afghanistan. Biden says Romney sees the world "through a Cold War prism," painting him as a relic of an era that no longer exists. Biden is the former chairman of the Senate Foreign Relations Committee.
