新闻天天译：奥巴马处理经济问题的能力

请翻译以下文字。
　　翻译内容：More Americans believe Obama’s ability to handle economic issue
　　More Americans believed that presumptive Democratic presidential candidate Barack Obama can better handle economic issue, the current top concern to American voters, according to a poll released on Thursday.
　　The poll conducted by CNN and the Opinion Research Corporation found that 50 percent of registered voters believe Obama, the Illinois Senator, would better handle the economy, while 44 percent prefer McCain in this regard.
　　The result of the poll revealed a big challenge for McCain on his way to the White House since the economy has been proved by many previous local and national polls to be the No. 1 issue concerning American voters in the 2008 presidential elections.
　　Another CNN/Opinion Research Corporation poll released last week showed that 42 percent of voters said economy is their most pressing concern, only 21 percent named Iraq war, which is the second most important issue to American voters.
　　However, the Thursday poll offers a positive news to McCain, saying that 54 percent of voters believe he is best suited to handle foreign policy issues, compared to 43 percent nodding on Obama.
　　答案：
　　更多的美国人相信奥巴马处理经济问题的能力
　　根据周四公布的一份调查显示，更多的美国人相信民主党预期总统候选人奥巴马能更好的处理美国选民目前最关心的问题——经济问题。
　　这项由美国有线电视和民意调查组织的调查发现：一半的注册选民相信奥巴马这位Illinois州的参议院议员能更好的处理经济问题。而在这个问题上有44%的人则倾向于麦凯恩。
　　调查结果给麦凯恩进驻白宫提出了一个巨大的挑战，因为此前大量当地和全国调查都证明经济是2008美国总统选举选民们第一关心的问题。
　　上周另外一个调查显示42%的选民认为经济是他们最急迫关注的问题，只有21%的认为是伊拉克战争，这是美国选民第二关注的问题。
　　但是，周四的调查给麦凯恩带来了有利的消息：54%的投票者相信他最适合处理对外政策问题，相比只有43%的人选了奥巴马。
