Obama makes gains in national polls
(CNN) -- Sen. Barack Obama has widened his lead over Sen. John McCain, according to CNN's latest "poll of polls."
The senator from Illinois is ahead of McCain in national polls by 3 percentage points, 47 percent to 44 percent. Obama was up by 2 points in the poll of polls released earlier Thursday.
McCain led in national polls last week, but by the weekend, the candidates were tied. Obama recaptured the lead for the first time in 10 days Wednesday.
The latest poll of polls consists of four surveys: CBS/The New York Times (September 12-16), Gallup (September 15-17), Diageo/Hotline (September 14-16) and American Research Group (September 13-15). It does not have a sampling error.
The economic crisis has given Obama and his running mate, Sen. Joe Biden, the opportunity to go on the offensive. Most Americans see Obama as more capable than McCain when it comes to the economy, polls indicate.

麦凯恩在上周国家民意测验中考(试大还领先，但到本周末，候选人受束缚了。在周三，奥巴马10天来重新获得领先地位。
这项最新的民意测验有四部分组成：9月12日到9月16日的CBS纽约时报民意测验，9月15日到9月17日的盖洛普民意测验，9月14日到9月16日的diageo热线调查，9月13日到9月15日的美国调查组的调查。这项测验不存在抽样的错误。
经济危机给奥巴马及他的幕僚约翰比本反攻的机会。民意调查显示，但谈到经济时，许多美国人认为奥巴马比麦凯恩更有能力。
