Romney's really going full-speed ahead with this "Obama = Evil Foreigner" business:

I just think it's kind of weird to remount Sarah Palin's attacks from four years ago. They didn't work then, and we've had four years of Obama being, you know, president of the United States of America and killing Osama bin Laden and such. But if Obama being foreign is what Romney wants to spend his time on, that's his prerogative as the assumptive Republican presidential nominee.
