America’s leadership in world affairs began to weaken with the unilateralism of Bush, and today’s economic problems are reinforcing this tendency. To reverse America’s decline, Obama needs bipartisan support for his (quite mainstream) policies, but so far the US Congress has shown no stomach for a principled approach to its legislative duties.
美国对世界事务的领导力随布什奉行单边主义开始削弱，而今天的经济问题正在强化这一趋势。奥巴马需要两党协力支持其（相当主流的）政策来扭转美国衰落的颓势，但截至目前美国国会对履行立法责任时秉承坚持原则的态度似乎不感兴趣。
