President of the United States
美国总统
What makes him powerful: Some say Obama's lame-duck period has set in early, considering the abysmal launch of Obamacare, the 16-day government shutdown, and the NSA's surveillance blunders. Still, POTUS remains in charge of the most powerful nation in the world.
权势所在：当想到奥巴马医保案的艰难推行，16天的政府关闭，国安局的监视丑闻的时候，有人说这些其实早已埋下隐患。当然，这位美国总统如今仍然掌控着这个世界上最强大的国家。
